Frequently asked questions
What happens to transparency when converting to JPG?
JPG can’t store transparency, so transparent areas become white — the standard behaviour. Convert to PNG or WebP if you need the transparency kept.
Why convert WebP to JPG?
WebP is great on the web but many upload forms, government portals and older apps reject it. Converting to JPG makes the file universally accepted.
Does converting lose quality?
PNG output is lossless. JPG and WebP use high-quality encoding (92%), visually indistinguishable for normal use. Repeated JPG→JPG conversions do accumulate loss, so convert from the original when you can.
Is it safe to use this tool with confidential documents?
Yes — and verifiably so. PDFAgent has no upload step: your file is processed by JavaScript running in your own browser and never leaves your device. You can open your browser’s network panel (or even go offline after loading the page) and confirm that no document data is transmitted.
