Frequently asked questions
How much smaller will my photos get?
A typical 3–5 MB phone photo saved at 1920 px on the long side and 80% quality usually ends up around 300–800 KB. For smaller files try 1280 px or 70% quality.
I need it under 2 MB.
1920 px and 80% quality brings almost every photo under 2 MB. The new size is shown in the list before you save.
Do iPhone HEIC photos work?
Yes. HEIC is converted automatically to JPG (or the format you choose).
Can I compress many photos at once?
Yes. Add them all and press Save all as ZIP to get a single ZIP file.
Are my photos uploaded?
No. Everything is processed in this browser on your device. Nothing is sent to a server.
