Photos inside the PDF, or pictures of the pages? Two tools, one decision
Extract Images returns the original image files stored in a PDF; PDF to JPG renders whole pages. How to choose, resolution consequences, scans.
UnboundPDF is a free suite of 54 PDF and image tools that run entirely in your browser — merge, split, compress, edit text, OCR in 126 languages, redact, sign, convert and archive to PDF/A. Your document is read and written by the page on your own device; there is no document-upload endpoint in the core tools, no account, no watermark and no daily cap. Every result can be checked — with the Network tab, or with the Document Passport the Workspace writes for a chain of steps.
The rule. Want the photo that is inside the document, at its stored resolution — Extract Images. Want the page as a picture — PDF to JPG.
| Extract Images | PDF to JPG | |
|---|---|---|
| Output | The embedded image files, one per image | One image per page |
| Resolution | The stored pixels, untouched | Whatever DPI you choose |
| Text and vectors | Not included (they are not images) | Painted into the page picture |
| Right for | Recovering photos, logos stored as rasters, scan pages | Thumbnails, slides, sharing a page as an image |
The resolution point
A 4,000-pixel photo placed small on a page is still 4,000 pixels in the file; extraction gives you all of them. Rendering the page at 150 DPI gives you the photo at the page's scale — a fraction of the pixels. For a photo, extract; for a layout, render.
Logos and charts
Vector logos and charts are drawings, not images; extraction returns nothing for them and says so. Render the page, or crop and render, for a picture of a vector.
Scans
Each scanned page is one image; extraction returns it at the scanner's resolution without re-sampling — cleaner than rendering.
Frequently asked questions
Why did Extract Images find nothing?
The PDF has no embedded rasters — text and vectors only. Render pages instead.
Why are extracted images bigger than on the page?
The PDF scaled them down for display; the stored image keeps its own pixels.
Can I get every page as a PNG?
Yes — PDF to JPG offers image formats and a DPI; choose PNG for exact pixels.
