Convert PGM to TIFF in seconds, free and unlimited. No upload, no sign-up, no watermark: your image never leaves your device.

Last updated

Quick answer: To convert PGM to TIFF, add the PGM file to the iHateFiles PGM to TIFF converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. TIFF supports transparency, which PGM never had. That helps if you plan to cut the background out afterwards.

Should you convert PGM to TIFF?

A safe conversion: PGM and TIFF are both lossless, so this is a change of container rather than a change to the picture.

Nothing is discarded

PGM and TIFF are both lossless, so every pixel survives the move intact. Convert back and forth as often as you like; the image does not degrade.

TIFF supports transparency, but there is none to recover

TIFF can store an alpha channel and PGM cannot, so nothing is gained here automatically. The result is fully opaque. Transparency has to be cut in an editor; no converter can work out which parts of a PGM were meant to be see-through.

What usually goes wrong

About the PGM. Converting a colour image to PGM throws the colour away for good. Keep the original if you might want it back.

About the TIFF. Because TIFF can contain many different compressions, a file that one program writes is occasionally one another program cannot read. Converting it to PNG settles the argument.

How to convert PGM to TIFF

  1. Add your PGM file. It is read from your disk and stays there.
  2. Check the settings. The output format is already set to TIFF.
  3. Press convert and the TIFF file is saved back to your device.

Questions

How do I convert PGM to TIFF?

Open this page, add your PGM file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.

Is this PGM to TIFF converter free?

Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.

Are my files uploaded anywhere?

No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.

Is there a file size limit?

No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.

Will converting to TIFF lose quality?

TIFF is lossless, so this step throws nothing away. If the original was already a lossy format, the damage it did cannot be undone, but nothing further is lost.

Can I convert several PGM files at once?

Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
