Drop one or more .tiff files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
TIFF to PBM
Converting a .tiff image to .pbm re-encodes the pixels for a different balance of size, quality, and support. Free, private, and validated — the file never leaves your browser.

Converting a .tiff image to .pbm re-encodes the pixels for a different balance of size, quality, and support. A .tiff file is a Tagged Image File Format raster, the long-standing archival and prepress standard for images that must not lose a single bit. Its tag-based structure lets one .tiff hold multiple pages, layers of metadata, and pixel formats from 1-bit fax scans to 32-bit floating-point channels.
A .pbm file is a Portable Bitmap: the simplest image format in common use, storing exactly one bit per pixel — black or white, with no grey and no colour. It carries a two-character magic number, the width and height, and then the pixels, and nothing else. For this route the practical draw is small enough to specify in a paragraph and to write from a shell script and uncompressed and lossless, so nothing is hidden between the header and the pixels — balanced against one bit per pixel — no grey, no colour, no transparency, which is worth knowing before you commit a large batch.
Why convert TIFF to PBM?
The practical trigger for this conversion is usually a mismatch: with .tiff, files are huge — often 10x a visually identical JPEG. Switching to .pbm buys you small enough to specify in a paragraph and to write from a shell script, which is why it is the better fit for masks, stencils and other genuinely two-tone raster data. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
TIFF vs PBM at a glance
| Aspect | TIFF image (.tiff) | Portable bitmap (.pbm) |
|---|---|---|
| Format type | Lossless — every pixel or sample is preserved exactly | Lossless — every pixel or sample is preserved exactly |
| How it stores data | structured as Image File Directories (IFDs) of numbered tags, allowing multiple images per file | two encodings share the extension: P1 stores pixels as ASCII 0 and 1 characters, P4 packs eight pixels into each byte |
| Strongest at | archival masters for museums, libraries, and digitization projects | masks, stencils and other genuinely two-tone raster data |
| Weak spot | files are huge — often 10x a visually identical JPEG | one bit per pixel — no grey, no colour, no transparency |
| Metadata | eXIF is itself structured as TIFF tags, so TIFF holds it natively, alongside XMP packets, IPTC records, ICC profiles, and GeoTIFF georeferencing tags | none beyond optional # comments in the header. There is no colour profile, no EXIF and no timestamp; a PBM carries dimensions and pixels and nothing else |
Pick PBM as the output
Select .pbm in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if PBM is selectable, the route is real and validated.
Convert on your device
Press Convert. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid PBM file. Outputs keep the original filename with the .pbm extension.
TIFF to PBM questions, answered
Will converting TIFF to PBM lose quality?
Since tiff is lossless-oriented and pbm is lossless-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .pbm itself requires.
Is it private to convert TIFF files here?
Yes — the .tiff file is processed inside your browser tab and never uploaded. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders. Close the tab and the file is gone from memory.
Where will the PBM file work?
Netpbm, ImageMagick, GIMP and most scientific imaging tools read PBM; browsers and consumer applications do not. Novus Convert decodes both the ASCII and the packed binary form locally and converts to PNG, JPEG, WebP and the other raster targets — which is usually the point, since PBM is a good interchange format and a poor delivery one.
Will the PBM file be bigger or smaller than my TIFF?
It depends on the content: two encodings share the extension: P1 stores pixels as ASCII 0 and 1 characters, P4 packs eight pixels into each byte. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my TIFF file?
In .tiff, eXIF is itself structured as TIFF tags, so TIFF holds it natively, alongside XMP packets, IPTC records, ICC profiles, and GeoTIFF georeferencing tags. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
Can I convert PBM back to TIFF?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .tiff → .pbm → .tiff is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
