Large photos slow down websites, fill up inboxes and stall client deliveries. This tool re-encodes your images with adjustable quality, so you get a much smaller file that still looks great. Everything runs locally in your browser using the Canvas API — there is no server, no queue and no upload.
Drag in a whole batch at once, tune the quality slider until the preview size looks right, and download all your compressed files in one click. JPEG is best for photos, WebP gives the smallest files for the web, and PNG keeps sharp edges for graphics.

Frequently asked questions
- Will compressing reduce image quality?
- You control the trade-off with the quality slider. Around 75% is usually indistinguishable from the original while cutting file size dramatically. Lower it for web use, raise it for print.
- Are my images uploaded anywhere?
- No. All processing happens on your own device in the browser. Your files are never sent to a server, which is why it works even offline.
- Which formats are supported?
- You can compress JPG, PNG and WebP, and convert between them. For photos, JPEG or WebP give the smallest files.
- Can I compress many images at once?
- Yes. Drop in a whole folder of photos and download them all with one click.
- Is it really free?
- Completely free, with no signup and no watermark. It is made by Exportlab, the media platform for photographers and videographers.
