How to use Image Compressor
- Drop one or more images into the upload area, or click to select them from your device.
- Drag the Quality slider to your preferred level and choose an output format (JPG, WebP or PNG).
- Keep Reduce image dimensions first enabled and set a max dimension if you want smaller files, then click Compress Images and download.
FAQs
Are my images uploaded to a server?
No. Compression happens entirely in your browser using the Canvas API, so your images are never uploaded or stored anywhere.
How much can I compress an image?
It depends on the original format and content. Lowering the quality slider and choosing WebP usually gives the biggest savings while keeping good visual quality.
What does Reduce image dimensions first do?
When enabled, images larger than the max dimension are scaled down before compression. This can dramatically reduce file size for very large photos.
Is the tool free to use?
Yes. Every Handio tool is free, with no sign-up, no limits and no watermarks.

Why use Image Compressor?
Shrink oversized images before they hit a limit you care about, whether that is an email attachment cap, an upload form, or a web page that needs to load fast on mobile data.
- Bring a 12MB camera photo under 2MB so it passes the attachment size limit on an email service.
- Compress product photos for an online store so the catalog pages load quickly without blur.
- Cut the size of screenshots before uploading them to a CMS that rejects large files.
Tips and Limits
Quality below about 60% can show visible artifacts, especially on text and screenshots, so preview the result before saving. Choosing WebP as the output format usually gives the biggest savings, and enabling "Reduce image dimensions first" helps a lot on very large photos. Process multiple files at once — all in your browser.
