Batch everything
Add a whole folder, tick the files you want, adjust the settings once and export them all as a single ZIP.
Convert image formats online
JPG, PNG, WebP and AVIF, with a quality slider and a live size estimate. Convert one image or hundreds at once.
🔒 Nothing is uploaded. Nothing is stored.
Every resize, crop and conversion runs on your own device using your browser’s built-in graphics engine. Your images are never sent to a server, never stored, and never seen by us — which also means the tool keeps working after the page has loaded, even if you go offline.
Drag to resize
Eight handles, exactly like resizing a shape in PowerPoint. Hold Shift to free the aspect ratio, double-click to snap back to the original size.
Free, no sign-up, no watermark
No account, no upload limit per day, no watermark burnt into your photos. The site is funded by ads, not by your files.
How to use it
Add your images
Drag files or a folder onto the page, paste from the clipboard with Ctrl+V, or click to browse.
Adjust once
Resize, crop or pick an output format. Leave “apply to all selected files” on to reuse the same settings for the whole queue.
Download
Export the current image on its own, or process everything and get a single ZIP file.
Frequently asked questions
Are my images uploaded to a server?
No. The whole editor runs as JavaScript inside your browser, so the image data stays in your device’s memory. Nothing is transmitted, nothing is written to a server, and there is nothing for us to delete afterwards.
Is there a limit on file size or number of files?
There is no server-side limit, only your device’s memory. In practice a modern laptop handles 100 photos of 50 MP without trouble; on a phone, work in smaller batches.
Which formats are supported?
JPG, PNG, WebP, GIF and BMP can be opened everywhere. AVIF and HEIC depend on your browser — the format buttons show which ones your browser can actually write, so you never get a broken file.
Does resizing reduce the quality?
Making an image smaller is done in gradual steps so edges stay sharp instead of turning jagged. Enlarging past the original size cannot invent detail, so it is switched off by default.
Is it really free?
Yes. The site is supported by advertising, so there is no subscription, no export credit and no watermark.
