PDF To Image
PDF To Image — runs in your browser. Inputs are not stored.
PDF → Image
Processed in the browser only. Files are not uploaded to a server.
How to use
- Choose the document under PDF file. One file at a time.
- Choose resolution: Normal (1.25), Sharp (1.75, default), or High (2.2).
- Press Convert. The first time, the pdf.js script is loaded from a CDN.
- Each page gets a preview and a “page N JPG” download link.
- A password-protected PDF or a blocked CDN shows a read-failure message. The file is not uploaded to a server.
- For many pages, start with Sharp (default). High uses more memory and time. The original PDF on disk is not changed.
Key concepts: in-browser PDF rendering
Conversion happens on this device only. The library is pdf.js (3.11.x) from jsDelivr plus a worker script. Each page is drawn on a canvas, then turned into a JPEG slice (quality about 0.92). There is no upload API; the selected file does not go to a server. If the internet is blocked and the CDN cannot load, conversion does not start.
Locked PDFs may not open because there is no password field. Ad blockers or a company network that blocks the CDN fail library load. Scan quality, page count, and device memory can make High slow or heavy on the tab. Form fields, video, and attachments remain as pictures only; text is not searchable.
Example
A 3-page handout at Sharp (1.75) produces three previews and links page-1.jpg through page-3.jpg. The done message includes the page count. A password PDF shows a note close to “This may be an encrypted PDF or the CDN may be blocked.” Converting with no file selected only asks you to choose a PDF. High (2.2) can look sharper but uses more size and time. Normal (1.25) keeps previews light, and the in-progress message switches to loading.

Frequently asked questions
Is the PDF uploaded to a server?
No. It is read and drawn as images in the browser only. The file does not leave during conversion either.
Do password PDFs open?
Often they fail because there is no password field. Unlock a copy and try again.
Why is a CDN needed?
pdf.js and the worker are loaded from jsDelivr. If they are blocked, conversion does not start. It cannot be used on an offline-only network.
Do you make PNG or merge into one image?
Only a JPG per page. There is no merge, PNG, or re-save-as-PDF option. Use another tool to stitch pages.
What if I set resolution to High?
Pixels grow so it can look sharper, but it uses more time and memory. For long documents start with Sharp; if the tab stalls, drop to Normal.
Does the original PDF change?
The file on disk is not touched. What you download is a newly made JPG; original comments and signatures remain only as they appear in the image. Closing the tab during conversion can drop the JPG URLs you made.
