Need help?PostScript to AVIF Converter
PostScript (.ps) is Adobe's 1984 page-description language for print and prepress; AVIF is the modern AV1-coded web image format. This converter renders each page of a PostScript file into an AVIF image — useful for pulling a figure or page out of a legacy .ps document and putting it on the web at a small file size. Because PostScript describes pages as vector drawing commands, the conversion rasterizes them at a fixed resolution, so the result is a pixel image, not a scalable document. If you need the file to stay exactly as authored, see the alternatives below before converting.
PostScript (.ps) Format at a Glance
| Property | Value |
|---|---|
| Type | Page-description language (vector text + graphics) |
| Created | 1982–1984 at Adobe (Warnock, Geschke, et al.); released 1984 |
| Rendering model | On-the-fly rasterization — text and curves are vector instructions resolved to dots |
| Pages per file | Often multiple; pages are delimited by the showpage operator |
| Native browser support | None — browsers do not display .ps directly |
| Best for | Print/prepress streams, TeX/dvips output, legacy archives |
| Largely superseded by | PDF, a direct descendant of PostScript |
AVIF Format at a Glance
| Property | Value |
|---|---|
| Standard | AV1 Image File Format (AVIF), released 2019 by the Alliance for Open Media |
| Codec / container | AV1 still-image frame stored in a HEIF container |
| Compression | Lossy by default, with a lossless mode |
| Bit depth | 8, 10, or 12 bits per channel; supports HDR and wide color gamut |
| Transparency / animation | Alpha channel and multi-frame animation both supported |
| Typical size | About 50% smaller than JPEG, and smaller than WebP, at similar quality |
| Native browser support | ~93% globally — Chrome 85+, Firefox 93+, Edge 121+, Safari 16.4+ |
How to Convert PostScript to AVIF
- Upload Your PostScript File: Drag and drop your
.psfile onto the page or click "+ Add Files". You can queue several files and convert them with the same settings. - Set the Conversion Quality (DPI): Open Advanced Options and pick a DPI under Conversion Quality. This is the resolution the vector page is rasterized at — 300 DPI is the default and good for crisp text; drop to 72 or 96 DPI for a smaller web image, raise it for fine detail.
- Adjust the Quality Preset and Background: Leave Quality Preset on Very High to preserve detail, or lower it to shrink the file. Under Image Transparency, the Color is White by default; switch it if you want a different flat background behind the page.
- Convert and Download: Click "Convert" and download your AVIF. A multi-page
.psproduces one AVIF per page. No sign-up, no watermark.
Frequently Asked Questions
Does converting PostScript to AVIF keep the vectors scalable?
No. PostScript stores pages as vector drawing commands, but rendering them to AVIF rasterizes everything to a fixed grid of pixels at the DPI you choose. The output is a flat image that gets blurry if you scale it up past that resolution. If keeping crisp, infinitely scalable text and lines matters, convert PS to PDF instead — PDF is a direct descendant of PostScript and preserves the vector document exactly.
What happens to a multi-page PostScript file?
PostScript documents are frequently more than one page, with pages separated by the showpage operator. Because AVIF is a single-image format, each page is rendered to its own AVIF image rather than being combined into one file. If you specifically need every page in a single document, PS to PDF keeps them together as one multi-page file.
Should I convert PS to PDF instead?
For most uses, yes. PostScript was effectively designed to become PDF, so PS to PDF is the faithful conversion — it keeps the exact layout, fonts, vectors, and all pages in one file that opens in any browser or PDF reader. Choose AVIF only when you specifically want a compact, web-ready raster image of a page or figure, not a document.
When is PNG a better choice than AVIF for this?
Pick PS to PNG when you need the widest possible compatibility or guaranteed lossless output. PNG opens in essentially every browser, image editor, and older app, and it is lossless by default — useful for line art, diagrams, and text where you want zero compression artifacts. AVIF wins on file size (roughly half of a comparable PNG for photographic content) and is the better pick when bandwidth matters and you only need modern browsers.
Will the AVIF have a transparent background?
Only if you ask for it. By default the Image Transparency color is set to White, so the page renders on a solid white background. AVIF does support an alpha channel, so you can produce transparency, but a PostScript page is normally opaque white paper — for clean transparency around line art, PNG is often the more predictable target.
Can older browsers and apps open an AVIF file?
Modern ones can — AVIF support sits around 93% of global browser usage, covering Chrome 85+, Firefox 93+, Edge 121+, and Safari 16.4+. But older browsers, many desktop image viewers, and some editors still can't open AVIF. If you are sending the image to an unknown recipient or an older system, PS to PNG or PS to JPG is the safer, universally readable choice.
How are my files handled, and how long are they kept?
Your .ps file is uploaded over an encrypted connection and processed on our servers — there is no in-browser-only mode for this conversion. Files are deleted automatically a few hours after conversion and are never shared or made public. No account or sign-up is required, and the output carries no watermark. In our testing, a single-page PostScript figure converted at 300 DPI produces a sharp, web-ready AVIF noticeably smaller than the same page saved as PNG, while keeping text edges clean.
