About Us
Bitinz is a free online image compressor for easier uploads and sharing. Smaller files, familiar quality, and no third-party uploads.

Upload and retention limits on this page are the service defaults until current settings load. Settings can change; check the upload area before sending files.
Four formats, one place
JPG (JPEG) and PNG can be compressed in their original format. Only still, lossy WebP is recompressed; lossless and animated WebP stay unchanged. AVIF optimization removes extra file information without re-encoding the picture; unsupported AVIF files stay unchanged. JPG and PNG can be converted to WebP. Conversion is lossy and can produce a larger file; AVIF to WebP is not supported.
Use the website for a few images, or the developer API to bring compression into your workflow.
Our own engine, with quality checks
Our own compression engine considers both smaller files and reliable image quality. Savings vary by image; when keeping the original format, we return the original if we cannot make it smaller. WebP conversion can produce a larger file.
Processed on our servers
Uploaded images wait in our object storage for processing. Temporary uploads are cleaned up after processing. Results are available for 4 hours from submission, after which downloads expire and files are cleaned up automatically. Images are never sent to a third party. Our Privacy Policy explains how files and account records are handled.
