TIFF to Text
Free TIFF OCR — multi-page and fax-compressed files included.
VisionParse converts TIFF files to editable text free in your browser, including multi-page TIFFs and fax-compressed scans.
TIFF is what scanners and fax servers produce, so we measured the variants they actually emit: an uncompressed TIFF (940.9 KB), an LZW-compressed one (69.3 KB) and a 1-bit Group 4 fax file (6.4 KB) all read at 100% character accuracy. A two-page TIFF came back with both pages read in a single pass.

TIFF, TIF — up to 3 MB. Your file is read on our servers in Frankfurt and deleted within the hour.
What this tool does, in numbers.
- ACCURACY
A Group 4 fax-compressed TIFF — 147× smaller than the uncompressed file — read at the same 100% accuracy in our measurement.
- LANGUAGES
VisionParse recognises 161 languages in TIFF files, and reads multi-page TIFFs in one pass.
- SPEED
VisionParse read a TIFF invoice in 0.51 seconds on an 8-vCPU server.
- LIMIT
An uncompressed A4 TIFF runs near 1 MB a page, so the 3 MB free limit fits about 3 uncompressed pages — LZW fits dozens.
- ACCESS
The TIFF to text tool requires no account, no email address and no payment card.
- RETENTION
VisionParse deletes free-tool TIFF files one hour after conversion.
Where the 100% at 6.4 KB (G4 fax) comes from.
Every figure on this page traces to a dated run on hardware we name. Nothing here is a vendor estimate.

- Claim
- Fax-grade Group 4 compression costs nothing: 6.4 KB and 940.9 KB versions of the same page both read at 100%.
- Method
- VisionParse standard recognition tier, single-threaded. Full methodology.
- Sample
- One synthetic invoice saved as uncompressed TIFF (940.9 KB), LZW TIFF (69.3 KB) and 1-bit Group 4 fax TIFF (6.4 KB), each read through the production pipeline and scored against ground truth.

- Group 4 is 1-bit black-and-white: ideal for printed text, destructive for photographs and grey stamps. A single synthetic document per variant is a small sample and is not a substitute for a corpus. These figures describe format behaviour, not general accuracy. A 500-document corpus run is scheduled and will supersede them.

What this tool gets wrong
Fax compression did not touch accuracy. Group 4 throws away everything except black and white, and for printed text that is exactly what recognition needs — 100% at one 147th of the file size. Old fax archives are better OCR material than they look.
1-bit compression destroys greys — and some content lives in the greys. Pencil annotations, rubber stamps and watermarks can vanish entirely in a Group 4 file, because they were grey and the format keeps only black. If the marginalia matters, scan to LZW or PNG instead.
Arabic-Indic numerals come back wrong. VisionParse reads Arabic script cleanly on the free tier, but ١٢٣ returned as 1#|. Numeric Arabic documents should use the AI extraction tier instead.
Three steps, no account.

When to use the API instead.
This page converts one file now. To convert files from your own software, the same engine runs over HTTP from Starter upward.
# same engine, from your code curl -X POST https://api.visionparse.app/v1/ocr \ -H "x-api-key: $VISIONPARSE_KEY" \ -F "file=@image.jpg" → 202 { "jobId": "c0df8e2c…" }
Use the API when
You convert more than a few files, convert on a schedule, or need results inside another system. Batch, webhooks and bounding boxes are API-only.
Frequently asked
Can you OCR a multi-page TIFF?
Yes. Multi-page TIFFs are read page by page in a single pass — our two-page test file came back with both pages, in order, in 0.65 seconds.
Do old fax TIFFs work?
Yes. Group 4 fax compression — the standard for fax archives — read at 100% in our measurement, identical to the uncompressed original at one 147th of the size.
Why is my TIFF so large?
Uncompressed TIFF stores every pixel raw: our single A4 page was 940.9 KB. Re-saving with LZW compression cut it to 69.3 KB with zero accuracy cost, because LZW is lossless.
Is the TIFF to text tool free?
Yes — 5 files a day with no account, no email and no card. A free account raises the allowance to 100 pages a month.
Do you keep my TIFF?
Free-tool files are deleted one hour after conversion, and no customer file is ever used to train models.
