Tamil Image to Text
Free Tamil OCR — measured at 95.4%, ligatures and all.
VisionParse extracts Tamil text from images free in your browser, reading the 247-combination syllabary with a dedicated Tamil model.
We measured 95.35% character accuracy on printed Tamil — a real figure scored against exact ground truth, on a paragraph with vowel signs attaching on both sides of consonants. Tamil is underserved by mainstream OCR; we publish the measurement so support means something. Errors concentrate where similar curves meet, not across whole words.

What this tool does, in numbers.
- ACCURACY
Tamil printed text read at 95.35% character accuracy in our measurement, scored against exact ground truth.
- SPEED
VisionParse read a Tamil paragraph in 0.23 seconds on an 8-vCPU server.
- LANGUAGES
The Tamil model reads the full syllabary — 247 consonant-vowel combinations, with vowel signs that attach before, after, above and below the consonant.
- LIMIT
Grantha letters used in loanwords (ஜ, ஷ, ஸ, ஹ) and dense older print score below the published figure.
- ACCESS
The Tamil image to text tool requires no account, no email address and no payment card.
- RETENTION
VisionParse deletes free-tool Tamil files one hour after conversion.

- Claim
- Printed Tamil read at 95.35% — measured against exact ground truth, with two-sided vowel signs handled correctly.
- Method
- VisionParse standard recognition tier, single-threaded. Full methodology.
- Sample
- A 129-character Tamil document paragraph rendered with Tamil (Brahmic syllabary)-correct Noto type through Pango (real text shaping), read through the production pipeline with the tam language model, and scored character-by-character against the exact source.

- Modern print; classical texts and ornate typefaces will score lower. 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
Two-sided vowel signs stayed attached to the right consonants. Tamil marks vowels on both sides of a consonant — கொ wraps its consonant entirely. The recognition kept these combinations intact rather than splitting them, which is where naive engines fall apart.
Similar curved letterforms are the main error source. Tamil distinguishes letters with subtle loop differences (ன/ண, ர/ா). At low resolution those merge, and they account for most of the 4.65% error. Sharper images close the gap.
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
Does it read Tamil ligatures and combined forms?
Yes. Vowel signs attaching before, after and around consonants — including fully wrapping forms — read as their correct combined characters in Unicode.
Can it handle Tamil-English mixed documents?
Yes. Invoices and forms from Tamil Nadu and Sri Lanka mix Tamil with English and digits constantly; the recognition reads both in one pass.
Why is the figure 95.35% and not higher?
Because it is measured, not asserted. Most errors are similar-shaped letter pairs at rendering size; sharper source images push accuracy up. We would rather publish the true number than a rounded one.
Is the Tamil image 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 Tamil documents?
Free-tool files are deleted one hour after conversion, and no customer file is ever used to train models.
