GUIDE · PDF LABHow to convert PDF to PNG or JPEG locally
Export pages while keeping the batch under control
Convert every PDF page into a file for messaging, presentations, image editors, or publishing. PDF Lab handles several documents at once and packages PNG or JPEG outputs in ZIP.
Conversion happens locally in the browser. PDFs render page by page on this device and are never uploaded to CHAMMILION.
JPEG is lighter for photos and scans. PNG is better for small text, lines, diagrams, and graphics, but creates larger files.
JPEG or PNG
JPEG is smaller; PNG preserves fine text and graphics.
Resolution control
High renders at 2× for zoom, crops, and printing.
Batch conversion
Process many PDFs while previews are created on demand.
Organized ZIP
Names preserve the source document and page number.
Local privacy
PDFs stay in the browser and originals are untouched.
Frequently asked questions
Are PDFs uploaded?
No. Rendering happens locally in this browser.
When should I use JPEG?
For scans, photos, and smaller files.
When is PNG better?
For small text, thin lines, diagrams, and tables.
Normal versus High?
High renders at 2× and uses more time and memory.
Can I convert many PDFs?
Yes. Convert a batch and download one ZIP.
Why does a long PDF use memory?
Every page needs an image canvas before export.
Is the original modified?
No. New image files are created for download.
How is this different from Split PDFs?
This creates PNG/JPEG; Split keeps pages as PDFs.
