Compress images without making them look worse
Shrink JPG, PNG and WebP files for websites, email and marketplaces. The work happens in your browser, so your photos are never uploaded.
How it works
Add your images
Drop in one photo or a whole folder’s worth. JPG, PNG, WebP and iPhone HEIC files all work.
Pick a quality
75 is a good default: most photos lose half or more of their size and look the same. Lower it for email, raise it for print.
Download
Save each file, or all of them as a ZIP. If a file can’t get any smaller, you get the original back untouched.
When a smaller file helps
Faster pages
Images are usually the heaviest part of a web page. Smaller files load faster and score better in PageSpeed and Core Web Vitals.
Upload limits
Forms, marketplaces and job sites often cap uploads at 1, 2 or 5 MB. Compress until you’re under.
Email attachments
A dozen phone photos can easily pass 25 MB. Compressed, they fit in one message.
Private by design
Files are processed on your own device. Location and camera data (EXIF) are removed from the output as a side effect.
Frequently asked questions
How much smaller will my photo get?
It depends on the photo. A typical 4 MB phone picture comes out at around 0.5–1 MB at quality 75. Screenshots and graphics saved as PNG often shrink even more when they become WebP or JPG.
What does “Auto” format do?
JPG and WebP stay in their format. A PNG without transparency becomes a JPG, which is far smaller for photos. A PNG with transparency becomes WebP, which keeps the transparent areas.
Are my images uploaded?
No. Compression runs in your browser using its own image encoder. The files never reach our servers, which is also why there’s no size or count limit apart from your device’s memory.
Why did a file not get smaller?
Some images are already well compressed. If the result would be bigger than the original, we keep the original and say so, rather than hand you a worse file.
