PaddleOCR vs Marker
Both are alternatives to AWS Textract. Here's how they stack up — verified facts, no spin.
Also searched as Marker vs PaddleOCR — same comparison, one verdict.
PaddleOCR is open source (Apache-2.0) and Marker is not (GPL-3.0 with commercial revenue condition) — so the real question is whether you want to own the document ai & ocr stack or rent it.
PaddleOCR
The strongest open OCR engine, and the best at non-Latin scripts.
PaddleOCR is a comprehensive OCR toolkit covering text detection, recognition, table extraction, layout analysis and key-value extraction, with support for around eighty languages. Its non-Latin script handling — Chinese, Japanese, Korean, Arabic — is clearly the best of the open options, and it ships lightweight mobile-scale models alongside the accurate server ones. Apache-2.0. If raw recognition accuracy on difficult scans is the constraint, this is the engine.
Marker
The best PDF-to-Markdown quality here — check the licence first.
Marker converts PDFs to Markdown with the highest fidelity of anything in this list: it handles equations, code blocks, tables and multi-column layouts, and optionally uses an LLM pass to improve difficult sections. For academic papers and technical documents the output quality is noticeably ahead. The caveat we would rather state than have you find in a licence review: Marker is GPL-3.0 with an additional revenue condition from its maintainer, so organisations above a revenue threshold need a commercial licence. Free for research and for smaller organisations, but not unconditionally.

PaddleOCR
Strengths
- +Best-in-class open recognition accuracy on difficult scans
- +Around eighty languages, with excellent non-Latin coverage
- +Includes table, layout and key-value extraction
- +Lightweight models for edge and mobile deployment
Trade-offs
- −Built on the PaddlePaddle framework — an extra dependency to adopt
- −Documentation is stronger in Chinese than in English
- −Output needs more post-processing than Docling's Markdown
Marker
Strengths
- +Best PDF-to-Markdown fidelity of the options here
- +Handles equations, code blocks and complex tables well
- +Optional LLM pass for difficult pages
- +Runs entirely locally
Trade-offs
- −Not unconditionally open source — revenue-gated commercial terms
- −GPL-3.0 copyleft affects how you can distribute derived work
- −GPU strongly recommended for reasonable throughput
Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose PaddleOCR
if you want the source and the option to fork it, and best-in-class open recognition accuracy on difficult scans.
Choose Marker
if best PDF-to-Markdown fidelity of the options here.
Neither, yet
if both carry a real cost you should weigh first — built on the PaddlePaddle framework — an extra dependency to adopt, and not unconditionally open source — revenue-gated commercial terms. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
PaddleOCR vs Marker — common questions
Is PaddleOCR a better fit than Marker for document ai & ocr?
It depends on what you are optimising for, and the honest split is this: PaddleOCR scores 92 to Marker's 70 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. Marker earns its place on a different axis — best PDF-to-Markdown fidelity of the options here. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
PaddleOCR keeps its data local or in open formats, so leaving is an export rather than a negotiation. Marker is still self-hostable, so the files stay on your server either way — but it is not local-first by design, so check what its export produces before you rely on it.
Can I self-host PaddleOCR or Marker?
Both can be self-hosted. The difference is what it costs you in time rather than whether it is possible — see the setup and maintenance rows above.
Are PaddleOCR and Marker both alternatives to AWS Textract?
Yes — both appear in our AWS Textract comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off AWS Textract and now choosing between the two replacements, which is a narrower and much easier question.
