Frequently Asked Questions

Can I extract single pages instead of converting the entire PDF?

Yes. Each converted page has an individual "Download JPG" button, allowing you to save only specific charts, slides, or certificate pages.

What is the resolution and quality of the exported JPG files?

Our renderer outputs crisp JPEGs at 92% quality with 2x retina oversampling, ensuring fine print, footnotes, and vector diagrams remain sharp and readable.

Is there a file size limit for PDF conversion?

Because processing happens locally in your device RAM, you are not restricted by cloud bandwidth caps. Large PDFs with hundreds of pages convert smoothly.

Does this tool work on mobile phones?

Yes. LocalDoc is responsive and works smoothly on iPhone Safari, Android Chrome, and tablets without requiring any app installations.

Are my PDF documents uploaded to external servers?

No. LocalDoc operates strictly client-side. Your files never leave your browser sandbox, ensuring absolute privacy for confidential documents.

PDF to JPG — Resolution & Colour Space Reference

Frequently Asked Technical Questions

What DPI settings are available for PDF to JPG export?
LocalDoc offers 72 DPI (web-optimised), 150 DPI (standard quality), 300 DPI (print quality), and custom DPI up to 600. At 300 DPI, an A4 page renders to 2480×3508 pixels — suitable for professional printing.
How are colour spaces handled during conversion?
PDF pages may contain CMYK, RGB, or greyscale colour spaces. LocalDoc's WebAssembly renderer converts CMYK to sRGB automatically using an ICC profile-aware colour transform.
Are PDF fonts rendered accurately in the JPG?
Type 1, TrueType, and OpenType fonts are rendered using the pdf.js font engine with sub-pixel antialiasing. CID fonts (common in CJK documents) require the embedded font to be present in the PDF for accurate rendering.
Can I extract specific page ranges?
Yes. Enter a range such as "1,3,5-9,12" to extract only those pages as separate JPG files. All pages are packaged into a single ZIP download.
