Need help?Convert PDF to APNG Online
This tool renders each page of your PDF as a separate, still APNG image — one file per page, numbered in page order. A multi-page PDF gives you multiple downloads, not a single animated file. The output is effectively a truecolor PNG inside an APNG container: full 24-bit color with an 8-bit alpha channel, and it opens anywhere a normal PNG does. If what you actually want is an animated page-flip of the whole document in one file, use PDF to GIF — that converter does assemble the pages into a single looping animation.
How to Convert PDF to APNG
- Upload Your PDF File: Drag and drop your PDF onto the page or click "Upload" to pick it from your device. The file is sent over an encrypted connection and processed on our servers.
- Set Conversion Quality (DPI): Choose the render DPI — 72 DPI for a small web preview, the default 300 DPI for crisp print-grade text, up to 1200 DPI for fine detail. Higher DPI means sharper pages but larger files and longer processing.
- Set the Background: Use the Image Transparency option (default White) to choose the color filled behind any transparent page content.
- Convert and Download: Click "Convert" and download the result — one APNG per page, so a 10-page PDF produces 10 numbered images. No sign-up, no watermark.

Frequently Asked Questions
Why is my APNG not animated?
Because this converter exports each PDF page as its own still image — there is no frame assembly on the APNG path, so nothing animates regardless of page count. If you want a looping page-flip of the document in a single file, convert with PDF to GIF instead; that path maps one page to one animation frame.
What do I get from a multi-page PDF?
One APNG file per page, numbered in page order. A single-page PDF produces one image; a 20-page PDF produces 20. Each file stands alone, so you can keep only the pages you need.
What DPI should I pick for readable pages?
For on-screen use, 150 DPI keeps body text legible while holding file size down. The 300 DPI default is the safe choice for documents with small text or fine line art. Going to 600 or 1200 DPI mainly helps when you plan to zoom in — it multiplies the pixel dimensions of every page image.
Will the output be larger than the original PDF?
Often yes, especially across many pages. A PDF stores text and vectors compactly, while each output image is a full raster of one page at your chosen DPI, and PNG-style compression is lossless. If the total is too large, drop the DPI to 96 or 150.
Is APNG supported in modern browsers and apps?
Since each output file is a still image, it displays anywhere PNG does — viewers that don't know APNG simply treat it as a normal PNG. The APNG format itself was folded into the official PNG specification by the W3C in 2025 (PNG Third Edition, June 24, 2025), and about 94.7% of browsers in use support it per caniuse.
Are my uploaded PDFs kept private?
Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared or made public.
