How it works
Add files
Drop photos onto the page or choose them - several at once is fine.
Adjust the settings
Compression starts automatically. Optionally lower the quality or set a maximum file size in KB.
Download the result
Download the compressed photos one by one or all at once as a ZIP.
Limitations
- Files up to 256 MB are supported; the actual limit also depends on the free memory of your device.
- The size limit in KB is reached by lowering the quality and, if that's not enough, by scaling the image down - but by no more than 4 times on each side. If the file still doesn't fit, you get an error rather than a file over the limit.
- With a size limit, an animated GIF is compressed only by reducing the number of colors.
Frequently asked questions
How do I reduce photo size without losing quality?
For JPG and WebP keep the quality around 80 - the difference is invisible while the file gets several times smaller. PNG is compressed losslessly: the optimizer repacks the data without touching pixels.
Can I compress a photo to a specific size, e.g. 100 KB?
Yes. Set a size limit in KB in the settings - the quality is picked automatically, and if that's not enough, the image is scaled down slightly.
What happens to iPhone HEIC photos?
HEIC can't be saved in the same format, so the photo is compressed to JPG, which opens on any device.
