Combine PDFs into One Long Image

Select two or more PDF files. Every page is rendered in file order and joined vertically into one PNG or JPEG image. Processing takes place in your browser; large documents may exceed browser memory limits.

PDFs to One Image workspace

If the workspace does not load, open the tool in a separate tab.

How to use

  1. Select at least two PDF files.
  2. Choose PNG or JPEG output, rendering scale and (for JPEG) quality.
  3. Click Combine PDFs into One Image and wait for the download.

Important limitations

This creates one tall raster image, not a searchable PDF. Text and vector content become pixels. Very long PDFs may need a lower rendering scale or fewer files. Keep your original documents.

Before you use Combine PDFs into One Long Image

Use Combine PDFs into One Long Image with a readable PDF file that you are permitted to process. Keep the original file as a backup, check page order or selected options before running the operation, and open the downloaded PDF to confirm that the pages and text look correct.

Check the result

Confirm that the output opens in a PDF reader, the page count and order are correct, and any required text or images remain visible. Password-protected, damaged, very large, or unusual PDFs may not work in every browser.

Common questions

Which files should I select?

Choose PDF files only unless the workspace explicitly lists another supported format.

Why might processing fail?

Try a smaller or unprotected PDF, reload the page, and make sure the browser libraries have finished loading.

Does this replace the original?

No. Keep your original file; review the downloaded result before deleting or sharing anything.

Privacy reminder: Do not use confidential or personal files unless you are authorised to process them and are comfortable with the tool’s processing method. Keep a backup of important source files.

PDF to one image: what to expect

This tool renders PDF pages and combines them into one tall raster image. It is useful for a quick visual reference, but text becomes pixels and may no longer be searchable or selectable. Very long PDFs can create large images and consume substantial browser memory.

Keep the original PDF. If the output is too large, try fewer pages or a lower rendering scale. Check that small text remains readable before sharing or printing. Do not use this conversion as a substitute for an accessible document when selectable text, document structure or high-resolution page-by-page output is required.
