Choosing quality for PDF to image conversion

Scale controls sharpness

Higher scale values render sharper page images, but they also use more memory and create larger files.

• Use lower scale for previews.
• Use higher scale for print or detailed diagrams.
• Test one page before rendering a long PDF.

PNG is predictable

PNG keeps text and line art crisp, while JPG can be smaller for image-heavy pages.

• Use PNG for documents and screenshots.
• Use JPG when photos dominate the page.
• Keep the original PDF until exports are checked.

Complex PDFs can fail

Encrypted, huge, or unusual PDFs may not render in every browser.

• Try a smaller page range first.
• Use a modern desktop browser for large files.
• Avoid closing the tab until downloads finish.
