How to compress, resize, and convert images
- 1. Drag your images onto the box above, or click to browse. Add as many as you like — they're processed in a batch.
- 2. Pick an output format. WebP gives the smallest files at great quality; JPEG is best for maximum compatibility; PNG keeps lossless quality and transparency.
- 3. Set a quality level and an optional maximum dimension. The preview and file-size savings update instantly so you can find the smallest size that still looks perfect.
- 4. Download a single image, or grab everything as a ZIP.
Every step happens locally in your browser using the Canvas API — your images are never uploaded to a server, which keeps even sensitive photos private and makes processing instant. There's no sign-up, no watermark, and no limit on how many images you convert.

Frequently asked questions
Are my images uploaded to a server?
No. Everything happens locally in your browser using the Canvas API. Your images never leave your device, which also makes processing instant.
Which format should I pick?
WebP usually gives the smallest files at great quality and is supported by all modern browsers. Use JPEG for maximum compatibility, and PNG when you need lossless quality or transparency.
Is there a file size or count limit?
No hard limit — batch as many images as you like. Very large images (50MP+) may take a few seconds each depending on your device.
Is this really free?
Yes. The site is supported by ads, so every tool stays free with no sign-up and no watermarks.
