Best Free OCR Software 2026
We tested every tool that advertises a free tier or free plan with real documents to find out what you actually get before hitting a paywall. Several tools call themselves free but lock basic features behind a credit card — we flagged those.
What to Look For
- 1.Is the free tier actually free, or does it require a credit card upfront?
- 2.How many pages or documents can you process per month at no cost?
- 3.Which core features are locked behind paid plans?
- 4.Is output quality on the free tier the same as paid?
Adobe Scan
Adobe Scan is genuinely free with no page cap for basic OCR — scan a doc, get searchable PDF output, done. The mobile app is the best we tested for real-world capture conditions.
Pros
- ✓Completely free. No watermarks, no page limits, no catch
- ✓Auto-crop and perspective correction are genuinely good, even in tricky lighting
- ✓Syncs to Adobe Document Cloud automatically if you're an Acrobat user
Cons
- ✗Editing features are locked behind a paid Acrobat subscription
- ✗OCR accuracy drops in low light or on crumpled/damaged documents
- ✗Getting files out of the Adobe ecosystem takes extra steps
Google Document AI
Google Document AI gives you 1,000 pages/month free on its general processor, which is enough for many small teams. The output quality on that free tier is better than most paid tools.
Pros
- ✓$0.06/page with pay-as-you-go. No minimum commitment
- ✓Pre-built invoice, receipt, and W-2 processors that actually work well
- ✓Scales automatically within the GCP ecosystem
Cons
- ✗You need GCP knowledge to get it running. Not a click-and-go tool
- ✗Support quality varies. Don't expect the hand-holding you'd get from a dedicated vendor
- ✗Locks you into Google Cloud infrastructure
Lido
Lido's free trial lets you process enough documents to properly evaluate it — we extracted 50 invoices without paying anything. It's a trial, not a permanent free plan, but it's genuinely useful for testing.
Pros
- ✓No template setup at all. New vendor format? It handles it automatically
- ✓Flat $30/mo pricing. No per-page surprises or confusing tiers
- ✓We got our first extraction in under 5 minutes from signup
Cons
- ✗Not built for massive enterprise batch pipelines (tens of thousands of pages/day)
- ✗Fewer native integrations than AWS or GCP ecosystem tools
- ✗No offline or on-premise option
Amazon Textract
Textract's free tier covers 1,000 pages/month for the first three months, which is enough to build and test an integration. After that, pricing is pay-per-page with no monthly minimum.
Pros
- ✓$0.0015/page for text extraction. Cheapest cloud OCR API we found
- ✓Plugs straight into S3, Lambda, and the rest of the AWS stack
- ✓Fully serverless. No infrastructure to manage or scale
Cons
- ✗Locks you into AWS. Moving to another cloud later is painful
- ✗Fewer pre-built document processors than Google Document AI
- ✗Decent support costs extra via AWS Business or Enterprise plans
PDF.co
PDF.co has a free plan with 100 API credits/month — limited but enough for low-volume personal use. Good for developers who want to test PDF parsing without committing to a subscription.
Pros
- ✓Does more than OCR: conversion, merging, splitting, annotation all in one API
- ✓$0.02/call is cheap enough for low-volume projects
- ✓Has Zapier integration if you're not writing code
Cons
- ✗OCR accuracy is noticeably worse than Google Document AI or ABBYY
- ✗Documentation and support quality are inconsistent
- ✗Not good enough for production document processing
