Common questions
How do I compress multiple images at once?
Add all your photos, choose your settings once, and press Download all as ZIP. Every photo gets the same settings.
How many photos can I compress at once?
Up to 5 at a time on the free plan, and 50 with credits or Pro. Client Export takes up to 200.
Does a ZIP count as one download?
No. Each photo in the ZIP counts as one download, so a ZIP of 5 photos uses 5.
Are my photos uploaded to compress them?
No. The compressing happens in your browser, and your photos never leave your device.
Can I compress all my photos to under 200 KB?
Yes. Choose Target size and press 200 KB. If a big photo can't fit, tick Also shrink the pixels.
