Queue dozens of images, convert them in one session with per-file progress, and download everything as a single ZIP — privately, on your device.
How it works
Convert a whole batch to WebP without sending anything to a server.
01
Pick a file or drag it straight in — JPG, PNG, GIF and more are all welcome.
02
Slide between smaller and sharper. 80 is a great default for most photos.
03
It saves straight to your device the moment it’s ready — no upload, no waiting.
Why WebP
Learn
Instead of converting images one by one, drop a whole batch in and let them all process together. Each file shows its own preview and progress, and you can grab everything at once as a single ZIP — ideal for preparing a gallery, a product catalogue, or a blog’s worth of images.
Bulk conversion uses your device’s spare processing cores to convert several images in parallel while keeping the page responsive. Nothing is uploaded — even a hundred images stay entirely on your machine — so it is safe to batch-convert client work, screenshots or personal photos.
On phones and lower-memory devices the converter automatically processes fewer images at a time so your browser stays smooth.
Set the quality once before you start and it applies to the whole batch. If a single file fails — for example a corrupt image — it is simply marked and skipped, and the rest of the batch continues. You can retry or remove it without losing the others.
