PDF and images
A practical PDF and image conversion workflow
Convert PDF pages to images and images back to PDF without losing control of quality, size, or privacy.
Document summary
A practical guide to converting between PDF pages and images in the browser, with resolution, quality, and privacy guidance.
Key takeaways
- Match the output format to the destination before converting.
- Choose resolution by screen or print use, not by habit.
- Keep the original file until the converted output is verified.
- Prefer local conversion for documents with private content.
Choose the conversion direction first
PDF to image conversions suit slides, previews, and platforms that reject PDFs. Image to PDF conversions suit attachments, printing, and archives. Decide which direction your task needs before opening a tool.
For PDF to image, JPG keeps files small and works everywhere, while PNG keeps edges sharp for diagrams and text-heavy pages. For image to PDF, the source format matters less because the PDF embeds it directly.
Set resolution by destination, not by habit
Screen previews need only 1x to 1.5x scale. Retina displays and modern presentations look best at 2x. Print work benefits from 3x, but the file size grows quickly with the scale.
When converting images to PDF, choose Fit when exact dimensions matter, and A4 or Letter for standard printed documents. The margin setting controls how much empty space surrounds the image.
Verify before you delete the original
Open the converted PDF or image in a viewer and check the first and last pages, text sharpness, and margins. Raster output such as JPG and PNG cannot be edited as text, so confirm the content is complete.
Keep the original file until the converted output is verified in its destination. Re-encoding is lossy for JPG, so the source remains the highest-quality copy you have.
Keep documents private with local conversion
Every conversion on this platform runs in the browser. PDF pages are rendered with pdf.js and documents are assembled with pdf-lib, so files are never uploaded to a server.
This matters most for contracts, scanned IDs, and unpublished designs. A local converter avoids the storage, logging, and retention questions that server tools introduce.
