Turn HEIF photos into lightweight WebP files for the web.
Drop HEIF photos here or click to browse
Processing happens on your device. Nothing is uploaded.
Files are processed locally in your browser. They never touch our servers.
Sensible settings are applied automatically. Fine tune them only if you want to.
Drop multiple images at once and download everything together as a ZIP.
Use this tool when a HEIF photo is headed for a website or blog and file size matters. It re-encodes the photo to WebP locally in your browser, keeping it visually identical while making it much smaller and still supported by every modern browser.
Image optimization works best when you choose the right balance between file size, visual quality, dimensions, format compatibility and privacy. These tips help you get a cleaner result.
When you choose a file, your browser reads it locally and creates the processed version on your own device. CompressImage.ca does not receive the original image or the finished file.
That local-first approach is useful for personal photos, client work, screenshots, documents, product images and other files you do not want to upload to a third-party server.
The best tool depends on what you are trying to fix. Compression reduces file size, resizing changes dimensions, conversion changes format, cropping changes framing, and metadata removal cleans hidden information from the file.
| Goal | Best tool |
|---|---|
| Make a file smaller | Compress Image |
| Hit an exact file size | Compress Image to Size |
| Change image dimensions | Resize Image |
| Create WebP files for websites | Convert to WebP |
| Convert iPhone photos | HEIC to JPG |
| Remove hidden photo data | Remove EXIF |
These tools solve similar image optimization problems and work the same way: locally in your browser, with no required upload.
WebP files are usually smaller than JPG at the same quality and still open in every modern browser, so WebP is the better pick when a HEIF photo is headed for a website or blog.
Quality 80 to 90 keeps photos looking identical to the original while cutting the file size sharply. Lower settings shrink files further if loading speed matters more than fine detail.
Yes. WebP supports an alpha channel, so any transparency in the source HEIF is carried through to the converted file.
No. The HEIF photo is decoded and re-encoded entirely in your browser using WebAssembly, so it never leaves your device and there are no server-side size caps.
