BigTranslator vs DeepL: Which Is Better for Long PDFs?
Use BigTranslator for a long PDF when you need the layout kept. Use DeepL when the file is short and DeepL already accepts it.
DeepL is a strong document translator for files that fit its plan limits. People reach for it when they want high-quality text and a familiar product.
The gap shows up on a long PDF (a manual, a contract set, a research pack) that DeepL will not take because of file size or character count. To translate an entire PDF with BigTranslator, start on that page. Comparing Google instead? See BigTranslator vs Google Translate.
The short answer
Use DeepL if your PDF is already accepted by DeepL (it is under your plan's file-size and character limits) and you are happy with DeepL's output. That is the right tool for a short, clean file.
Use BigTranslator if you need a long PDF translated with the layout, images, and tables kept, up to 1,000 pages, and you want to pay once per document instead of a subscription. Start from $6.99.
DeepL's published docs cap PDFs by megabytes and characters, and those caps change by plan. They do not publish a single page-count limit. We will not invent one.
What DeepL actually publishes about PDF limits
These numbers come from DeepL's own file-format help page and API usage-limits page. If a number is not there, it is not on this page either.
1. File size and character caps, not a page count
DeepL limits each PDF by file size and by character count. A free DeepL account is listed at 5 MB and 100,000 characters per PDF. Paid web plans rise from there (examples on their help page include 10 MB, 20 MB, 30 MB, and 100 MB, with up to 1 million characters). DeepL API Free is listed at 10 MB and 500,000 characters. DeepL API Pro is listed at 100 MB and 1 million characters.
We did not find a published “maximum pages” figure on those pages. A 400-page scanned manual can blow a megabyte cap. A text-heavy 80-page report can blow a character cap. Page count alone is not the rule they publish.
2. Long files are the wedge
If DeepL already accepts your file, you may not need us. BigTranslator is built for the PDFs that chat tools and consumer translators reject as too large: files ChatGPT, Claude chat, and Google Translate will not take, and files that sit past DeepL's size or character caps.
BigTranslator translates up to 1,000 pages in one job and keeps formatting, images, and tables.
3. Layout on files that actually finish
DeepL's document product is designed to return a translated file in the same format, and it is a fair choice when the upload succeeds. We are not going to claim DeepL “always wrecks layout.” That is not what their product is for, and we have not published a side-by-side layout test on this page.
What we can say about BigTranslator: you get a translated PDF that keeps the original layout, images, and tables, page by page, on files up to 1,000 pages.
4. How you pay
DeepL document translation sits on subscription or character-based plans. Exact monthly prices change, so we are not quoting a DeepL sticker price here.
BigTranslator is pay per document, no subscription. Standard is $6.99 (1 to 100 pages), Large is $19.99 (101 to 250), Business is $49.99 (251 to 1,000).
5. Languages we can actually print
DeepL writes a broader set of languages than we can print as PDF output, including Chinese and Japanese. If you need those as PDF targets, DeepL may be the better fit (when the file is short enough).
BigTranslator lets you pick 71 source languages. About 45 of those can be written as PDF targets (Latin, Greek, and listed Cyrillic). Chinese, Japanese, Korean, Arabic, Hebrew, Thai, and Hindi or other Indic scripts are fine as a source into English or another renderable target. They cannot be written as PDF output yet.
Where DeepL is actually better
To be fair, DeepL has real strengths:
- •It is built for everyday document translation. If your PDF already uploads and the result looks right, stay there. You do not need a second tool.
- •It covers more written targets than we can print. DeepL can output languages our PDF writer cannot render yet, including Chinese and Japanese.
- •You may already have a seat. If your team pays for DeepL and the file fits the plan, that is the cheaper path for that one file.
- •Short files finish fast. A few pages of clean text is not the problem BigTranslator is priced to solve.
If DeepL already accepts the file and you only need a readable translation, DeepL is usually the better choice.
When the file is the problem
A 300-page technical manual with figures, or a 200-page bilingual contract pack, is where consumer translators usually stop. DeepL may reject that upload for size or characters. Google Translate often stops at 10 MB. Chat and Claude chat reject the same class of file as too large.
That is the job BigTranslator is built for. You upload the whole PDF, pick a renderable target language, and download a translated file that keeps the layout.

When to use BigTranslator instead of DeepL
Switch (or start here) if any of these are true for your document:
- DeepL already rejected the upload for file size or character count
- The PDF is long enough that you need up to 1,000 pages in one job
- You need the original layout, images, and tables kept
- You want to pay once per document, with no subscription
- You already tried a chat tool and it said the file was too large
- You compared Google Translate and hit the 10 MB wall
