Compress TIFF Files
TIFF files from scanners and print workflows are often stored uncompressed, at 3 or 4 bytes per pixel. Re-saving one as an optimised PNG keeps every pixel identical and usually saves a large share of the size; switching Save as to JPG makes it far smaller still for email and uploads. Only the first page of a multi-page TIFF is processed.

See the result and its file size on your actual image before processing the batch.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
Never bigger than the original
If compression cannot beat your file, the original is returned unchanged with a note.

Frequently asked questions
Can the file stay a TIFF?
Not smaller, here: this site's TIFF writer stores pixels uncompressed, so a re-saved TIFF would not shrink. PNG is the lossless alternative almost every app opens. If a recipient insists on TIFF, desktop editors such as GIMP or Photoshop can save TIFF with LZW or ZIP compression.
Is the PNG really lossless?
Yes for 8-bit images: every pixel is kept exactly. 16-bit TIFFs are reduced to 8 bits per channel, which is invisible on screen but matters for heavy photo editing.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
