Is this PDF to PNG converter really free?

Yes. Up to 5 files at a time, no signup, no catch. The free tier adds a small watermark to image output — Pro ($9.99/mo or $49/yr) removes it, raises the file size limit to 500 MB, and unlocks unlimited batch conversion.

Are my files uploaded to a server?

No — and you can verify it yourself. Open DevTools → Network tab, then convert a file. You'll see zero upload requests. Everything runs in your browser via WebAssembly. We never see your files.

How long does conversion take?

Usually 1–3 seconds for a typical file. The very first conversion on a fresh page load may take 5–20 seconds while the WebAssembly codec loads — after that it's instant. Your CPU does all the work locally.

What is the file size limit?

Free: up to 10 MB per file, 5 files per batch. Pro: up to 500 MB per file, unlimited batch. If you're working with large videos or RAW photos, Pro is built for that.

Can I batch convert multiple PDF files at once?

Yes — drop multiple files at once (or Ctrl/Cmd+click to select them) and they all convert in parallel. Free accounts handle up to 5 files per batch; Pro has no limit.

Will my document formatting survive conversion?

Standard formatting — text, headings, bold/italic, tables, and inline images — transfers reliably. Complex layouts with floating objects, custom fonts, or SmartArt may simplify. Always give the output a quick review before sharing.

Can I convert a password-protected document?

No — encrypted files can't be read without decryption, and we never ask for passwords. Remove the password protection first, then convert.

Does converting PDF to PNG lose quality?

No. Our converter renders each page at 150 DPI by default (up to 300 DPI for Pro users), producing crisp, pixel-accurate PNGs.

Can I convert a multi-page PDF to multiple PNGs?

Yes — each page of your PDF becomes a separate numbered PNG. You can download them individually or as a ZIP archive.

How private is this converter?

Completely private — by design, not policy. There is no upload endpoint. Files are processed using WebAssembly inside your browser tab and disappear the moment you close it. We collect only anonymous page-view counts; your file content is never seen or stored.

Why convert PDF to PNG?

If you've ever tried to open a PDF file and hit a wall — the app won't accept it, the website rejects it, or the preview just shows a broken icon — you already know why this conversion matters.

Portable Document Format is great for what it was designed for, but it has real-world limitations: not editable without acrobat or similar and image extraction requires specialized tools. The moment you step outside that original context, it gets frustrating fast.

Portable Network Graphics is the safer choice for Logos and UI assets, Screenshots, Images requiring transparency. Its main advantages — lossless compression — pixel-perfect quality and full alpha transparency (8-bit alpha channel) — mean it just works wherever you need it.

A few common reasons people end up here: - Their target app, site, or device doesn't accept PDF - They need a smaller file for email or upload (PNG often compresses better) - They need Portable Network Graphics's specific capability: lossless compression — pixel-perfect quality - Compatibility with older software that pre-dates Portable Document Format

The conversion is one-way: you get a PNG that works everywhere Portable Network Graphics is expected. The original PDF file is not touched.

Quality & file size: PDF to PNG

Typical file sizes: PDF 100–500 KB → PNG 8–25 MB.

Transparency: PDF does not support transparency. PNG preserves transparency.
