Need help?PS to APNG Converter
This is a niche, technical conversion: it rasterizes each page of a PostScript file into a separate, still APNG image — one file per page. PostScript (.ps) is a vector page-description language, so every page is rendered to a flat raster at your chosen DPI, with the vector instructions baked into fixed-resolution pixels. The result is a truecolor PNG in an APNG container: 24-bit color with full 8-bit alpha that displays anywhere a PNG does. Note that this converter does not assemble the pages into an animation — if you want a single file that flips through the pages, use PS to GIF instead. Output quality is governed entirely by the render DPI you pick.
PS Format at a Glance
| Property | Value |
|---|---|
| Full name | PostScript |
| Vendor / origin | Adobe Systems, 1982 |
| Type | Vector page-description language (also a full programming language) |
| Contents | Text and graphics defined as lines and Bézier curves, page by page |
| Resolution | Resolution-independent (vector) until rasterized |
| Native browser support | None — browsers cannot display .ps directly |
| Typical use | Print/RIP workflows, desktop publishing, legacy document exchange |
| Successor | PDF (device-independent container derived from PostScript) |
APNG Format at a Glance
| Property | Value |
|---|---|
| Full name | Animated Portable Network Graphics |
| Origin | Proposed 2004 by Stuart Parmenter and Vladimir Vukićević (Mozilla) |
| Standard status | W3C Recommendation since June 24, 2025 (folded into PNG Third Edition) |
| Color / transparency | 24-bit truecolor with full 8-bit alpha (vs GIF's 256 colors, 1-bit mask) |
| Compression | Lossless (zlib/DEFLATE) |
| Compatibility | Non-APNG decoders still render the file as a normal PNG |
| Native browser support | Firefox 3+ (2008), Chrome 59+ (2017), Safari 8+, Edge 79+ |
| Best for (this converter) | Crisp truecolor page stills with clean edges and transparency |
How to Convert PS to APNG
- Upload Your PS File: Drag and drop your .ps file onto the page or click "Add Files" to pick it.
- Set Conversion Quality (DPI): Choose the render resolution — the default is 300 DPI (print-grade); pick a lower DPI for small previews or up to 600 or 1200 DPI for sharper text and fine detail.
- Set Transparency: Image Transparency lets you keep a white page background or composite onto a chosen color.
- Convert and Download: Click Convert. Each PostScript page comes back as its own still APNG image. Files upload over an encrypted connection, are processed on our servers, and are deleted automatically after a few hours — no sign-up, no watermark.
Frequently Asked Questions
Why does my PS to APNG output look pixelated or blurry?
PostScript is vector, but an APNG is a fixed grid of pixels, so the converter has to rasterize each page at a single resolution. If text or fine lines look soft, raise the Conversion Quality (DPI) — 300 DPI is print-grade, and 600 or 1200 DPI gives crisper edges at the cost of a larger file. Lowering DPI does the opposite.
Why is my APNG not animated?
By design: this converter exports each PostScript page as a separate, still APNG image rather than stitching pages into an animation. A still APNG behaves exactly like a static PNG in every viewer. If what you actually want is one animated file that flips through the pages, use PS to GIF — that path assembles the page-flip animation for you.
Does the APNG keep PostScript's vector scalability?
No. Vector data is resolution-independent, but rasterizing to APNG bakes the artwork into pixels at the DPI you chose, so it can no longer scale up cleanly. If you need a result you can still resize losslessly, keep a vector target instead — for example PS to PDF preserves the original page geometry.
Will APNG transparency survive the conversion?
APNG supports full 8-bit alpha, so transparency can be carried through. PostScript pages, however, usually render against an opaque page background. The Image Transparency setting controls this: keep "White" for a solid backdrop, or composite onto another color. True see-through output depends on the source page actually having transparent regions.
Is the APNG standard still maintained?
Yes — and it is now formally part of the spec. The W3C elevated APNG to official Recommendation status on June 24, 2025, folding it into the PNG Third Edition. It is supported natively by Firefox, Chrome, Safari, and Chromium-based Edge, and a non-supporting decoder still renders the file as a normal PNG.
Why convert PostScript to an image format instead of keeping it as PS?
Browsers and most modern viewers cannot open .ps directly, since PostScript was built for printers and RIPs, not screens. Rasterizing produces self-contained images that display everywhere a PNG does, one per page of the source document. PS to PNG gives you the same per-page stills with the standard .png extension.
How does APNG output quality compare to GIF for these pages?
Per page, APNG keeps full 24-bit truecolor with 8-bit alpha, so gradients, images, and anti-aliased text come through clean, while GIF is limited to 256 colors and usually dithers. The two paths also differ in output shape: this converter produces one still image per page, whereas PS to GIF combines the pages into a single animated file.
Is this conversion private?
Yes. Your PostScript file is uploaded over an encrypted (TLS) connection, rendered on our servers, and the file is deleted automatically after a few hours. There is no sign-up, no watermark on the output, and files are never shared or made public.
