A Compressor.io alternative that skips the server
ShrinkPix compresses the same formats Compressor.io does — JPEG, PNG, WebP — plus AVIF, GIF and BMP, entirely in your browser instead of uploading files to a server. That removes any per-file size limit and means the images never leave your device.
Compressor.io offers both lossy and lossless compression through a clean, simple upload interface, and it is a solid choice for occasional single-file use. Like most compression tools it is server-side, which means an upload step for every file and a stated 10MB per-file limit — fine for web-sized images, restrictive for camera originals or large exports.

What to know
- Compressor.io supports SVG compression, which this tool does not — SVG is markup, not a pixel format, so it needs a different kind of optimiser.
- For photographs and large batches, running the compression locally avoids both the 10MB cap and the one-file-at-a-time workflow.
Frequently asked questions
- What is Compressor.io's file size limit?
- 10MB per file on its free web tool, and files are processed one at a time.
- Is there a batch alternative to Compressor.io?
- Yes — ShrinkPix accepts many files at once, with no per-file size limit, and returns a ZIP of the results. It runs the compression in your browser rather than uploading to a server.
