Capture2Text vs Umi-OCR: Which Free OCR Fits You?
Capture2Text and Umi-OCR are the two most recommended free OCR tools for Windows — and they’re free in very different ways. This is an honest comparison of two open-source projects, not a sales pitch: both cost nothing, both are legitimate, and the right choice depends entirely on what you OCR.

Where Capture2Text Wins: Instant Screen OCR
Capture2Text is a screen-first tool. The workflow is muscle memory: Win+Q, drag a rectangle, text lands on your clipboard — with optional Google Translate in the same keystroke. Nothing to open, no window to manage. The unique “Bubble OCR” mode is built for speech bubbles in manga and game dialogue, and manga readers in particular still swear by it.
For grabbing a snippet of on-screen text right now — an error message, a line in a game, a subtitle — Capture2Text is faster than any document OCR tool, Umi-OCR included.
Where Umi-OCR Wins: Batch and Documents
Umi-OCR (MIT license, actively developed, ~39.7k stars on GitHub) is a document-first tool. Point it at a folder of images or a multi-page PDF and it chews through the whole batch, preserving layout and producing searchable PDFs — things Capture2Text fundamentally cannot do. If your job is “digitize this stack of scans,” Umi-OCR wins by a mile.
So Which Should You Use?
Use Capture2Text for instant screen grabs, hotkey-driven capture, on-the-fly translation, and manga/game dialogue (Bubble OCR).
Use Umi-OCR for batch image OCR, multi-page PDFs, searchable PDF output, and layout restoration.
Use both if your work mixes the two — they’re both free, portable, and small enough to coexist. One handles the screen, the other handles the scanner.

Frequently Asked Questions
Is Umi-OCR really free?
Yes — Umi-OCR is open source under the MIT license, completely free for personal and commercial use, with no ads or paid tiers.
Can Umi-OCR replace Capture2Text for screen captures?
Mostly, but not perfectly. Umi-OCR does screenshot OCR, but Capture2Text’s hotkey-first workflow (Win+Q, drag, done) and its built-in translation and Bubble OCR modes remain faster and more specialized for on-screen grabs.
Which is better for Japanese or Chinese text?
Both handle CJK text. Capture2Text’s Bubble OCR and vertical-text support make it the favorite of manga readers; Umi-OCR’s PaddleOCR engine is strong on Chinese document batches.
