Image Compressor
Shrink JPG, PNG & WebP. Pick quality, get a smaller file.
What does the image compressor do?
The freeimgtool image compressor shrinks the file size of a JPG, PNG, or WebP without obvious visible loss. Pick a quality level between 10 and 95 on the slider, hit compress, and download the smaller file. The page shows the size before and after plus the percentage saved. There is no signup, no email gate, and no watermark added to the output.
Behind the scenes the compressor uses the Pillow imaging library and JPEG's baseline encoder. Quality 70 is a good default for the web — most viewers will not see the difference from the original, but the file is usually 60–80% smaller. Drop to quality 50 if you need a really tiny file for an email attachment.
How to use it
- Click the upload box and pick an image (up to 5 MB).
- Drag the quality slider. 70 is a strong default. Lower for smaller files, higher for sharper output.
- Click Compress.
- Compare the before / after / saved row.
- Click Download to save the smaller file.
Why compress your images
Smaller image files make web pages load faster. Faster pages rank better on Google, lose fewer visitors, and use less mobile data on the viewer's phone plan. Email providers cap attachment size, so a one-megabyte compressed photo gets through where a four-megabyte original bounces. WhatsApp and messaging apps re-compress on the way through their servers, so pre-compressing protects more of the original quality.
Who uses it
Bloggers and content writers preparing images for upload. Online sellers shrinking product photos for Etsy, eBay, or Shopify listings. Real-estate agents emailing property galleries. Students attaching photos to homework portals. Developers shaving page weight to hit Lighthouse targets. Anyone with a phone photo that is "too big to attach."
Frequently asked questions
Is this image compressor free?
Yes. No signup, no premium tier, no daily cap on normal personal use. Display ads keep the site free.
What is the maximum upload size?
Five megabytes per file. That covers nearly every phone photo. If the source is larger, resize first with the image resizer and then compress.
What quality should I pick?
70 is the safe default. Drop to 50 for the smallest files with still-acceptable quality. Raise to 85 for sharper output on product photography. Above 90 the file barely shrinks at all.
Does it work on PNG and WebP?
Yes. PNG and WebP uploads are accepted. Output is JPEG — the most universally supported and most compressible format. If you need to preserve transparency, use the format converter instead.
Will it strip my photo's EXIF data?
Yes. Re-encoding to JPEG drops EXIF metadata. That is a small privacy bonus — GPS coordinates and device identifiers get removed in the same step.
Is the output watermarked?
No. The downloaded file is clean.
Does it work on phones?
Yes. The upload box accepts photos straight from the camera roll or the camera.
Is my photo stored?
Uploads are kept only long enough to return a download link and are removed automatically afterward. See the privacy policy for details.
