Image Compressor
Adjust file size and quality, then export a lighter image quickly
Compression runs in your browser first and does not upload the original image to the server. Useful for web uploads, social sharing and faster mobile pages.
Step 1
Upload your source image
Supports PNG, JPG, and WEBP. Drag a file here or select one, then compress it and export as JPG, WEBP, or PNG.
Useful before uploading
Website covers, product images and article illustrations can all be compressed first to reduce loading time.
Control size and dimensions together
Limit the target file size and shorten the longest edge at the same time to balance quality and transfer speed.
Original stays local first
Compression and preview run in your current browser first, which is better for sensitive images.
Step 2
Adjust compression settings
Start with the target size first, then decide whether to switch format or lower quality based on the result.
The smaller the target, the stronger the compression usually becomes. Useful when you need to control upload size.
If the original image is very large, limiting dimensions first is often more stable than only lowering quality.
Raise this when image details matter more. Lower it further if you need a smaller file.
Photos usually work best as JPG or WEBP. To keep transparency, prefer the original format, PNG or WEBP.
Step 3
Generate and download
After compression, you will see a before-and-after comparison together with the file size change.
How To Use
1. Upload a PNG, JPG or WEBP image. A cleaner source image usually gives you more flexibility when balancing size and quality.
2. Start with the target size, then fine-tune the longest edge and quality. That usually works better than dropping quality too hard at the start.
3. If you still need a smaller file, switch the export format to JPG or WEBP and compress again.
4. Check the before-and-after preview together with the file size change, then download the result for upload, sharing, or web use.
FAQ
Which setting should I adjust first when compressing?
Start with the target size, then shorten the longest edge if needed, and only lower quality further when you still need a smaller file.
When are JPG or WEBP better output choices?
Photos, posters, and product images with smoother color transitions usually shrink much more as JPG or WEBP. WEBP is often the better choice for the web.
How do I keep transparency while compressing?
If the source image uses transparency, keep the original format or export WEBP. Exporting to JPG merges transparent areas into a solid background.
