Adobe Acrobat vs free OCR tools: Adobe OCR online and on the desktop

There is no honest number for Adobe. We did not run Acrobat or its free online tool on our test scans, and Adobe does not publish an error rate, so any ranking of Adobe against other tools would be a guess. If accuracy decides it, put one of your own pages through both and compare the results line by line.

What we can show is how far free tools differ from each other. On our scans, a local Tesseract run got 55.3% of the Urdu page's characters wrong and 20.4% of the Arabic page, while FastOCR got 9.1% and 2.6%. Lower is better. The chart and the Urdu example below hold the full runs.

Only in part. Adobe's free online OCR tool accepts a PDF and runs text recognition, but you sign in to download the searchable result, and Adobe says the file is deleted unless you sign in to save it. The page names English, German, Spanish, French and Portuguese "and more". Making text searchable in PNG, JPG or TIFF files is described under a seven-day Acrobat Pro trial. Checked 4 November 2026.

On the desktop, Adobe's pricing page lists "Turn scans into editable PDFs" for Acrobat Pro and Studio and leaves it off Acrobat Standard. Acrobat Pro costs US$19.99 a month on an annual plan billed monthly and US$29.99 month to month. The page shows a free-trial button for Pro without saying how long the trial runs.

FastOCR takes the other route. Images are free with no sign-up and no watermark, and each one comes back as text, a one-page searchable PDF, Word and Markdown. A scanned PDF needs a free account, and the pricing page shows what the free and paid plans include.

More than English. Adobe's language help page for Acrobat Export PDF names English (US and UK), Danish, Dutch, Spanish, French, Japanese, Russian, Italian, Traditional Chinese, Norwegian, Portuguese, Finnish and Swedish. It tells you to pick the language before you run OCR on Japanese, Chinese or Korean pages. It does not list Arabic, Urdu, Persian, Hebrew, Hindi, Bengali, Tamil or Thai.

That is a gap in what Adobe documents, not a test result. The page covers Export PDF, so the Recognize Text dialog in the desktop app may offer more, and we did not install Acrobat to check. For a script that is not listed, run one page first. The language and plan breakdown goes through each Acrobat plan.

FastOCR picks the language of each page by itself, so a mixed Urdu and English letter needs no setting. On our scans it got 9.1% of Urdu characters wrong, 2.6% of Arabic and 2.2% of Tamil; lower is better.

In Acrobat, open the scanned PDF, choose All tools, then Scan & OCR, then In this file. Set the page range and language, and select Recognize Text. Adobe's help page says Acrobat then creates a searchable text layer in the PDF. For a pile of files, In multiple files takes several PDFs and writes the processed copies to a folder.

FastOCR does the same job in a browser tab. A scanned PDF keeps its page image and gains an invisible text layer, and the text copies out in reading order, right-to-left scripts included. Sign in with a free account for PDFs; images need none.

Adobe's online tool page lists editing recognized text, e-signatures and fillable forms as Acrobat Pro features. If you need to change words on a page, sign it or fill a form, that is Acrobat's job, and FastOCR will not replace it. FastOCR reads a document and writes text, a searchable PDF, Word and Markdown.

For small PDF jobs the free browser PDF tools merge, split, compress and sign, and the files stay in the browser.

If you want to recognise text on your own computer without a yearly plan, the free Mac and Windows apps from FastOCR work offline and save a searchable PDF, text, Word or Markdown. They use Apple Vision and Windows OCR, so none of the figures on this page describe them. Both are unsigned public betas, and your system warns you the first time you open one.

They are not PDF editors. Acrobat stays the better desktop choice when OCR is one step in a longer PDF workflow.
