Free Image Compressor — JPG, PNG & WebP
Compress up to 20 JPG, PNG, WebP or AVIF images, up to 50 MB each. Image processing stays in your browser.
Adjust JPG or WebP quality, compare file sizes, and download your results. To change pixel dimensions first, use the bulk image resizer.

JPG, PNG, WebP, AVIF · max 50 MB each · up to 20 images
Quality affects JPG and WebP; PNG export ignores this slider. Same-format compression keeps the original if it is smaller. Changing format can increase file size. JPG replaces transparency with white. AVIF output depends on browser support; choose JPG or WebP if Original fails. This tool preserves pixel dimensions and does not guarantee a specific KB target.
Supported Formats
The browser re-encodes your images. Check the result before replacing an original; image metadata may be lost during conversion.

How to reduce image file size
Compress an image in three steps
Select up to 20 JPG, PNG, WebP or AVIF images, each up to 50 MB. Choose an output format and quality, then compress. Compare the original and output sizes before downloading; inspect text, edges and small details at full size.
The tool preserves pixel dimensions. If you need fewer pixels, use the bulk image resizer first. To work toward a strict upload limit, follow our guide to compressing images under 100 KB. A specific file size is not guaranteed.
Before and after: a measured compression example
This illustrated test image was exported by this tool in Chrome 155 at WebP quality 80. Both files are 1000 × 600 pixels: the original PNG is 804,092 bytes and the WebP is 35,956 bytes (95.5% smaller). This is one synthetic example, not an expected saving for every image. Open both files at full size to compare text and fine lines.
Choose a format and quality
| Format | What to expect |
|---|---|
| JPG | Adjustable quality. Transparent areas become white. |
| WebP | Adjustable quality with transparency support. Check that your destination accepts WebP. |
| PNG | Preserves transparency; the quality slider does not control PNG compression. |
| Original | Keeps the input format. AVIF export depends on browser support; choose JPG or WebP if unavailable. |
Lower quality can reduce detail as well as file size. Savings depend on the image, format and browser. When the format stays the same, the tool keeps the original file if re-encoding would make it larger. Format conversions can produce larger files.
Prepare product images for marketplace listings
For a square listing image, make a copy of the original, crop to a 1:1 composition and resize to the dimensions required by the marketplace. Compress only after resizing, then check that labels, edges and product details remain clear at full size. These steps reduce file size; they do not establish that a marketplace will accept the image. Check the marketplace’s current seller requirements before upload.
For product photography, see the Daraz seller image preparation guide. You can also crop an image, resize to exact pixel dimensions, or remove a background before compression.
Browser processing and large images
Image processing happens on your device. Large dimensions can consume substantial memory even when the file is below 50 MB. On a phone, start with a few images and use smaller batches if processing fails. Keep an original copy when image metadata matters.
