Question 1

Do I have to sign up?

Accepted Answer

No. No email, no account, no social login. Drop a PDF, download PNGs. Entirely signed-out — we don't gate the output behind a modal because we don't need your email for anything.

Question 2

Is there a daily or monthly limit?

Accepted Answer

No. Convert one PDF or a hundred; there is no counter, no quota, no '3 per day' wall. The conversion runs on your CPU, not ours, so there is nothing to ration.

Question 3

Will the output have a watermark?

Accepted Answer

Never. Output PNGs are identical to the PDF page — no logo, no corner stamp, no 'converted with…' text. Many cheaper free PNG tools slap a logo on the output so you'll pay to remove it. We never built that funnel because the tool costs us nothing to run.

Question 4

Is there a hidden Pro tier that unlocks things?

Accepted Answer

Not for PDF to PNG. Paid tiers unlock AI features like chat and translate. The image converter is identical at any tier — no locked DPI, no gated losslessness, no 'remove watermark' upsell.

Question 5

What's the catch?

Accepted Answer

None at the conversion level. Your PDF bytes never upload, so there's no server cost for us and no meter on you. Honest truth: we give the tool away free because a small fraction of users later buy AI features. That's the full economic model.

Question 6

What DPI does it output at?

Accepted Answer

Default is 150 DPI — good for on-screen or light print use. Configurable up to 300 DPI for sharp print output, 600 DPI for archival scanning workflows. The DPI picker is visible in the main tool UI, not hidden behind a 'Pro' gate.

Question 7

Why choose PNG instead of JPG for PDF pages?

Accepted Answer

PNG is lossless — every pixel is preserved exactly. That matters for documents with sharp text, line art, tables, or screenshots where JPG's block artifacts become visible. For photo-heavy pages without text, JPG often produces a smaller file with no visible difference; we provide both tools so you can pick. Tables + diagrams + text → PNG; natural photos → JPG.

Question 8

Is the output size bigger than JPG?

Accepted Answer

Yes, typically 3–5× larger, because PNG stores every pixel losslessly. A 1-page document PDF might be ~300 KB as a PNG vs ~90 KB as a JPG. If file size matters more than perfect fidelity, JPG is the right choice; if you're archiving or designing, PNG keeps everything.

Question 9

Does it work for scanned PDFs?

Accepted Answer

Yes. The converter renders each PDF page regardless of whether the content is native text or a scanned raster. For scanned documents, PNG is often a better choice than JPG because it doesn't compound the scanner's original compression artifacts with additional JPG quality loss.

Question 10

How is this different from a screenshot?

Accepted Answer

Screenshots capture what's rendered on your screen at the current zoom — usually 100 DPI or whatever your monitor reports. This converter renders each PDF page at the DPI you pick, from the original vector data when available, producing a sharp image that scales beyond screen resolution. No zoom-in blur.

Question 11

Is there a file count or size limit?

Accepted Answer

No artificial limit. Practical ceiling is your browser's memory, typically around 500 MB per file on modern laptops. Batch-convert as many files as you want — because the conversion runs on your CPU, we don't ration by count.

Question 12

Does the file get uploaded anywhere?

Accepted Answer

No. The PDF bytes never leave your browser. DevTools → Network tab will show no upload request carrying your file. This is why the tool can stay free: there's no server-side bandwidth or CPU bill to pass on to you.

Question 13

Does it work on my phone?

Accepted Answer

Yes. Safari on iOS, Chrome/Firefox on Android all support the underlying canvas PNG encoder. Smaller PDFs convert comfortably on a mid-range phone; very large scanned docs may be slow due to mobile memory limits.

Question 14

What's the catch with other 'free' PDF-to-PNG tools?

Accepted Answer

The usual traps: (1) secret JPG re-encoding inside a .png container, costing you the lossless guarantee; (2) alpha-channel flattened to white without warning; (3) watermark in the corner; (4) 3 files per day limit; (5) signup required after first use; (6) size cap around 10–25 MB. None of these apply here because the tool runs locally and has no server-side meter.

Question 15

Can I use this for commercial work?

Accepted Answer

Yes. The output PNGs are yours — no license restriction, no commercial-use clause to read. Freelancers, agencies, and small businesses use this exactly as they would a paid desktop converter.

Question 16

What libraries power this?

Accepted Answer

PDF parsing: PDF.js (Mozilla, open source). Rendering: browser's native canvas API. PNG encoding: the browser's built-in toBlob('image/png'), which is bit-preserving. All open source, all runs on your device — you can inspect the client code in DevTools → Sources.
