Visiting the museum

Open Tuesday to Sunday, from 10 am to 6 pm.

Last entry at 5:30 pm.

Closed on Mondays.

Read the translation, copy it into your notes or save it as TXT.

Sample French-to-English translation, not an actual Convertok result.

Save the translation as plain text

Open your TXT download in a text editor to read it or add notes. Keep the original PDF alongside it for images, fonts and table layout.

Check your PDF before translating

A PDF can look readable on screen while storing its words as an image. This translator needs text it can extract.

Selectable text

The museum closes at 6 pm.

You can select the words and copy them into a text editor. Check that they paste in the right order.

A scan or photograph

If the page is an image with no text layer, use a separate OCR tool first, then check the recognised text.

Two types of PDF. Selecting and copying a sentence is a useful first check; it does not guarantee that every page will extract correctly.

Scans and image text

Scan-only pages and words inside pictures or charts are not supported.

Use OCR elsewhere to create selectable text. Compare the recognised words with the scan before translating.

Columns and tables

Text extraction can mix columns or separate a value from its heading.

Paste a short passage into a text editor to check the reading order. Keep the source table beside the translation.

Size and length

The limits are 100 MB per PDF and 150,000 characters of extracted text.

A small file can still exceed the text limit. Prepare a smaller PDF with the relevant pages and note their original page numbers.

Ways to use your PDF translation

Start with the information you need from the document. Keep enough surrounding text to understand the author’s meaning.

Research and study

Read an article or course handout in another language. Copy a useful passage into your working notes.

Keep the original citation. Check specialist terms and the surrounding paragraph before quoting the author.

Work documents

Understand a report, handbook or set of written instructions. Save TXT if you want to add notes in a text editor.

Compare conditions, responsibilities and figures with the source. Check diagrams in the original PDF.

Trips and events

Read opening hours, arrival instructions or booking information. Copy the details you need into your plans.

Check dates, local times and exceptions. In the museum example, closing time and last entry are different.

Check the details that change the meaning

AI translation can misread an ambiguous word or miss an exception. Review the parts that affect what you will do next.
Times, dates and amounts
Compare the value, currency and unit, even when the notation changes. In the example above, 17 h 30 means 5:30 pm; it is the last entry time, not the closing time.
Names and specialist terms
Check names, product codes and abbreviations. If a term has a specific meaning in your field, use that meaning consistently when editing your working copy.
Conditions and exceptions
Look for words such as “not”, “unless” and “only”. Check who must act, what they must do and when the instruction applies.

If a passage still seems unclear, read the surrounding paragraph in the source and ask someone who knows the language to check the meaning.

Know what you send for AI translation

The PDF stays on your device; its extracted text is sent to an AI service. That text can include personal or confidential details from the document.
  1. 01

    PDF on your device

    Your browser reads the PDF and extracts its text.

  2. 02

    Text sent for translation

    An AI service processes the extracted text.

  3. 03

    Translation to keep

    Read the result, copy a passage or save TXT.

How it works: the browser extracts the text, an AI service translates it, and you can save the result.

Use documents you have permission to process with AI. Read the Privacy Policy before translating sensitive material.

Convertok is operated by Uptraff Ltd. For help with Translate PDF, email [email protected] with your browser, file size and the problem you see. Describe the issue first; you do not need to attach the PDF to your initial message.

Questions about PDF translation

Is this online PDF translator free?

Yes. You can translate PDF text with Convertok without creating an account or installing software. The file and text limits still apply.

Which languages can I translate a PDF into?

Choose from 30 target languages in the tool’s language selector. Check the available choices before starting your translation.

Can I download the translation as a PDF?

Convertok offers translated text to read and copy, plus a TXT download. It does not create a translated PDF or preserve the source document’s page design.

Can I translate a scanned PDF?

A scan-only PDF has no text for this tool to translate. Use a separate OCR tool to create a PDF with selectable text, then check the recognised words. Text inside images and charts is skipped.

How large can my PDF be?

Choose a PDF up to 100 MB with up to 150,000 characters of extracted text. These are separate limits. For a longer document, prepare a smaller PDF containing the pages you need.

Why is some text missing or in the wrong order?

Missing text may come from image-only content, while columns can appear in the wrong order during extraction. Try copying text from the affected area into a text editor. If nothing pastes, that area may need OCR. If the order is wrong, compare the translation with the source page.

Why use a PDF translator instead of pasting individual passages?

You can work through the document’s text in page order with page numbers for reference, then copy passages or save TXT. You do not need to copy each passage into a separate translation box.

Can I use the translation as an official document?

The result is an AI-generated text translation, not a certified translation. Ask the organisation receiving your document which translation format and credentials it requires.

Start with the PDF you want to read

Choose your document and a target language. Read the translation page by page, then copy it or download it as TXT.
