Unlike TinyPNG
HEIC and AVIF — formats most free compressors skip
TinyPNG doesn’t accept HEIC files (iPhone’s default photo format since iOS 11) and doesn’t output AVIF (the format Google recommends for Core Web Vitals). This tool does both. HEIC input is fully supported — upload directly from iPhone without converting first. Choosing AVIF as the output format typically produces files 40–50% smaller than JPEG at equivalent visual quality. The quality slider, output format selector, and metadata-strip option work on HEIC and AVIF exactly as they do on JPEG and PNG. All processing runs server-side via ImageMagick; nothing is stored after download.
A Free TinyPNG Alternative
AT USE compresses JPEG, PNG, WebP, AVIF, HEIC, BMP, TIFF, and ICO files — up to 20 MB each — with no file count limit and no account required. TinyPNG’s free web plan caps each file at 500 KB and does not support HEIC input (iPhone’s default photo format since iOS 11) or AVIF output (30–60% smaller than JPEG at equivalent quality). AT USE has no paid tier.
Frequently asked questions
What is the best way to compress an image without losing quality?
Use a quality setting between 75–85% for JPEG and WEBP images. This range removes invisible data while preserving detail the eye can see. HEIC and AVIF achieve even smaller files at the same perceived quality because they use more efficient codecs.
How do I compress an image online for free?
Drop your image above, choose a quality level (the default 82 is a solid balance), pick an output format, and click Compress Image. Download your compressed file instantly — no account required, no watermarks.
Which image formats can I compress?
This tool accepts JPEG, PNG, WEBP, AVIF, HEIC, BMP, TIFF, and ICO as input. You can output to JPEG, PNG, WEBP, or AVIF. Switching to WEBP or AVIF on output often gives the biggest file size reduction.
What is the file size limit?
Each image can be up to 20 MB. The tool processes one image at a time. For batch compression of up to 12 images at once, use the Image Optimizer.
Are my images stored after compression?
No. Compressed files are held on the server only long enough for you to download them, then automatically deleted. Nothing is retained beyond your session.
Can I compress HEIC files from my iPhone?
Yes. HEIC is fully supported as an input format — a feature TinyPNG and most free online compressors do not offer. Upload your HEIC directly without converting first. You can output to JPEG, WEBP, or AVIF after compression.
Does this tool output AVIF?
Yes. Select AVIF in the output format dropdown. AVIF typically produces files 40–50% smaller than JPEG at equivalent visual quality and is supported by all major modern browsers: Chrome 85+, Firefox 93+, Safari 16.4+, and Edge 121+. It’s the recommended format for web images where file size matters most.
Is AT USE a free alternative to TinyPNG?
Yes. AT USE compress-image handles JPEG, PNG, WebP, AVIF, HEIC, BMP, TIFF, and ICO files up to 20 MB each with no file count limit and no account required. TinyPNG’s free web plan caps at 500 KB per file. AT USE also supports HEIC and AVIF output which TinyPNG does not. Both are free; AT USE has no paid tier.

Image compression reduces file size by removing data the human eye cannot detect at normal viewing conditions. When you open a JPEG photograph at 8 MB and apply quality 80 compression, the result is typically 1.5–3 MB — a 60–80% size reduction — with no visible difference on screen or in print at standard display sizes. That gap directly affects how fast a web page loads, how much bandwidth a CDN bill consumes, and whether an email attachment bounces back for exceeding an inbox size cap.
AT USE Compress Image runs entirely on the server using ImageMagick — the same open-source engine that powers professional publishing workflows, digital asset management systems, and print prepress pipelines. You upload a file, choose a quality level and output format, and download a compressed result in seconds. Nothing is re-encoded by a browser canvas (which introduces a second quality-loss pass regardless of your quality setting), and no file is retained after download.
Quality settings and what they mean
For JPEG and WEBP output, the quality slider runs from 1 to 100. Quality 85 is the default: at this setting, a compressed JPEG is visually indistinguishable from the original under typical viewing conditions, including zoom to 100% on a retina display. Quality 75 cuts file size by another 20–30% relative to quality 85, with no visible artifact for most photographic content. The visible threshold for JPEG artifacts — blocky areas in smooth gradients, ringing around sharp edges — starts at quality 65 and becomes pronounced below quality 50. For most web publishing, quality 75–85 covers every practical use case without guessing.
PNG output uses lossless compression (DEFLATE). There is no quality setting for PNG — every pixel in the output matches the input exactly. PNG compression level controls encoding speed, not quality: higher compression levels take slightly longer to encode but produce smaller files at identical visual output. For PNG, the only way to meaningfully reduce file size is to convert to a lossy format (JPEG or WEBP) or reduce the color depth or dimensions before compressing.
Why format choice reduces file size more than quality does
Switching from JPEG to WEBP at the same quality setting typically reduces file size by 25–35% for photographs and 50–70% for graphics with flat colors. AVIF achieves a further 10–20% reduction over WEBP at equivalent visual quality, though encoding takes longer and AVIF is still not supported by Safari 16 and earlier. For web images targeting modern browsers (Chrome 85+, Firefox 93+, Safari 16.4+, Edge 121+), WEBP is the best default choice. For maximum compatibility, keep JPEG.
HEIC input is supported, which TinyPNG and most free online compressors do not offer. iPhone and recent iPad cameras shoot HEIC by default. Uploading HEIC directly — rather than first exporting a JPEG from Photos — preserves the full 14-bit HDR data through the conversion step. The compressed output JPEG or WEBP is produced from the highest-quality source, not a pre-compressed export.
What server-side processing means for quality
Browser-based compression tools encode images through the HTML5 canvas API, which runs the browser's own JPEG or WEBP encoder on top of your quality setting. This introduces a second encode pass: the image is decoded, drawn to a canvas, then re-encoded with whatever quality the browser internally applies before applying your slider. Server-side encoding with ImageMagick applies your quality setting directly to a single decode-encode pipeline, with no intermediate re-encoding step. For large files or batch operations, this difference compounds.
Common use cases
- Optimizing images for a CMS or e-commerce platform — A developer building a Shopify or WooCommerce store receives product photos at 5–10 MB each from a photographer. Uploading at that size puts the page load time for a category grid (12 products, 12 images) at 60–120 MB total weight. Compressing each to WEBP at quality 80 brings each image to 150–400 KB — a category page weight of 2–5 MB that loads in under 2 seconds on a standard connection.
- Reducing photos before sending over email — A property photographer delivers a shoot of 30 interiors at 8–12 MB per JPEG (shot on a full-frame mirrorless body). A 30-image email attachment is 240–360 MB — above the attachment limit of every major email provider. Compressing to quality 82 brings each image to 1–2 MB, making the full delivery fit in a single 30–60 MB email.
- Batch-preparing social media assets — A marketing coordinator creates Instagram and LinkedIn posts daily. Raw exports from Canva or Figma as PNG run 1.5–4 MB per image. Compressing and converting to WEBP at quality 82 before upload brings each file to 100–300 KB — faster to upload from a slow office connection and within Instagram's recommended file size for best preview rendering.
- iPhone HEIC archive compression — A photographer has a folder of 500 HEIC files from an iPhone 15 Pro shoot (raw HEIC files run 8–15 MB each). The archive totals 4–7 GB. Converting and compressing to JPEG at quality 85 reduces each file to 1–3 MB, bringing the archive to 500 MB–1.5 GB. The compressed JPEG versions are usable in any software without a HEIC codec installed.
- Reducing file size before printing a photo book — A photo book service accepts JPEG uploads per page and enforces a 150 MB total project limit. A 60-page book at 6 images per page = 360 images. At 5 MB per image, the project is 1.8 GB — 12× the limit. Compressing each image to quality 85 at the book's required print resolution brings the total to 80–120 MB.
Frequently asked questions
What quality should I use for web images?
75–85 covers most web use cases. At quality 80, a JPEG photograph compresses to 30–50% of its original file size with no visible difference at normal browser zoom. At quality 75, the same image is 25–40% of the original — a further 10–15% reduction that is also invisible at normal viewing. Below quality 60, JPEG compression artifacts become noticeable on photographic content, particularly in smooth gradients and sky areas.
Does compressing a PNG reduce its quality?
No. PNG uses DEFLATE lossless compression. The quality slider has no effect on PNG output — every pixel in the compressed PNG matches the input exactly. PNG file size is reduced by encoding efficiency, not by discarding visual data. To meaningfully reduce a PNG's file size, convert it to WEBP (lossy at your chosen quality) or JPEG. Use PNG only when transparency is required or lossless accuracy is non-negotiable.
How much smaller will my file be?
Depends on the input format and content. For JPEG input at quality 85 output: typically 40–70% smaller than an unoptimized original from a digital camera. For PNG to WEBP at quality 80: typically 50–80% smaller. For HEIC to JPEG at quality 85: typically 30–60% smaller, since HEIC is already efficiently compressed. The result card shows the exact size reduction as a percentage after every compression.
Can I compress HEIC files from my iPhone?
Yes. HEIC is a supported input format — an advantage most free online compressors (including TinyPNG, Squoosh, and CompressPNG) do not offer. Upload your HEIC directly. You can compress the HEIC and output to JPEG, WEBP, AVIF, or PNG in the same step, without first exporting from iPhone's Photos app.
Is the compressed file stored on the server?
No. The compressed output is held in a temporary location only long enough for your download to complete, then automatically deleted. Your original uploaded file is also deleted at the same time. Nothing is retained between sessions.
Should I use WEBP or AVIF for web images?
WEBP is the safer default. It is supported by all major browsers since Chrome 32, Firefox 65, Safari 14, and Edge 18. AVIF achieves 10–20% better compression at the same quality but requires Safari 16.4 or later — users on iPhone models running iOS 15 or earlier cannot display AVIF. If your traffic analytics show fewer than 5% of visitors on Safari 15 or earlier, AVIF is worth considering. Otherwise, WEBP covers 98%+ of web users with smaller files than JPEG.
Is this tool free?
Yes — completely free. No account required, no watermarks on output, no usage cap beyond the 20 MB per-file technical limit.
Is AT USE a free alternative to TinyPNG?
Yes. AT USE's compress-image tool handles JPEG, PNG, WebP, AVIF, HEIC, BMP, TIFF, and ICO files — up to 20 MB each — with no file count limit and no account required. TinyPNG's free web plan caps file size at 500 KB per file. AT USE also supports HEIC (the default iPhone format since iOS 11) and AVIF output, neither of which TinyPNG offers. Both tools are free; AT USE has no paid tier.
