How to use
When it helps
Large photos slow down blogs and online stores, and they often hit attachment limits in email and chat apps. A phone photo is usually 3 to 8MB, far more than you need for viewing on a screen.
This tool re-encodes your photos so they look almost the same while taking up much less space. At 70 to 80% quality, files typically shrink to 20 to 40% of the original size. Re-saving also strips EXIF data such as GPS location, so you share less personal information when you post photos.
If a job application or official form says something like "under 300KB", pick a target size. The tool lowers the quality step by step until the file fits under the limit.
FAQ
Are my photos uploaded to a server?
No. Compression happens inside your browser, and your files are never sent or stored anywhere. It even works offline once the page is loaded.
How much quality do I lose?
At around 75% quality, most people cannot tell the difference at normal screen sizes. For photos you will zoom into or print, we recommend 85% or higher.
Why do PNG files barely shrink?
PNG is a lossless format, so the quality setting does not apply. If you do not need a transparent background, switch the output format to JPG or WEBP for much smaller files.
The file got bigger after compressing.
Re-saving an already well-compressed photo at high quality can make it larger. Lower the quality or choose a target size. Results larger than the original are shown in yellow.
Does it work with iPhone HEIC photos?
Yes. HEIC photos are converted to a regular image first and then compressed. With Keep original selected, they are saved as JPG.
