How to use it
- Drop up to 30 images, or choose them.
- Pick a goal or set format, quality and maximum dimensions once for all of them.
- Start. Up to three files run at the same time, depending on your device.
- Retry any file that failed, or remove it.
- Download single files, or everything as a ZIP.
Formats and limits
- Opens
- JPEG, PNG, WebP, GIF (first frame), AVIF where your browser decodes it, BMP
- Saves
- JPEG, PNG, WebP, in a ZIP or one by one
- 30 files per batch on the free plan. Large batches of big photos need a lot of memory, especially on phones.
- The ZIP is built in memory, so very large batches may be slow on older devices.
