PostScript to HEIF Converter

PostScript to HEIF Converter

PostScript (.ps) is Adobe's page-description language: a fixed-layout document that describes each page as instructions for a printer or interpreter, not as a bitmap. HEIF (.heif) is a modern ISO/MPEG image container that here stores an HEVC-coded still — far smaller than JPEG at the same visual quality. This converter rasterizes each PostScript page into a HEIF image at a DPI you choose; a multi-page .ps yields one HEIF per page, delivered as a ZIP.

How to Convert PostScript to HEIF

1. Upload Your PostScript File: Drag and drop or click "+ Add Files". Batch upload works — drop several .ps files and each is rasterized independently.
2. Set Conversion Quality (DPI): This matters most. The default is 300 DPI (print quality); drop to 150 DPI for screen viewing, 96 DPI for thumbnails, or raise to 600 DPI for archival output. File size grows roughly with the square of DPI.
3. Tune Quality Preset, Color, and Resolution (Optional): Set the Image Compression Quality Preset to Very High (the default) for detailed pages or Medium to shrink files. Pick an Image Transparency Color (White by default) to fill the page background, and use Image Resolution to scale the rendered page independently of DPI.
4. Convert and Download: Click Convert. Each page becomes its own HEIF image; download individually or as a ZIP. Files upload over an encrypted connection, are processed on our servers, and are deleted automatically a few hours later. No sign-up, no watermark.

Frequently Asked Questions

Is HEIF the same thing as HEIC?

Not quite. HEIF (ISO/IEC 23008-12, standardized by MPEG in 2015) is the container. HEIC is the common case of that container holding an image coded with HEVC (H.265) — the standard reserves the .heic extension for HEVC-coded files. In everyday use the names are used interchangeably, and the images iPhones produce are HEIC. This converter outputs the HEIF/HEIC family from your PostScript pages.

Will the text in my PostScript file still be selectable after converting to HEIF?

No. PostScript describes text as instructions, but rasterizing flattens each page into a pixel grid, so the text becomes part of the picture and can no longer be selected, copied, or searched. If you need the layout preserved with selectable text, convert to a document target instead — see PS to PDF. HEIF carries no text layer.

What can actually open a HEIF file?

In the Apple ecosystem, HEIF opens natively on macOS High Sierra (10.13) and later and iOS 11 and later, per Apple's documentation. Windows 11 can view HEIF after installing the HEIF Image Extensions (and an HEVC extension for HEIC) from the Microsoft Store. In browsers, only Safari renders HEIC inline, starting with Safari 17 — Chrome, Firefox, and Edge do not, which caniuse puts at roughly 14% global native support. If your recipient isn't on Apple hardware, convert to JPG instead.

Why convert PostScript to HEIF instead of JPG?

Efficiency and quality headroom. HEIF stores stills with HEVC coding, so at the same visual quality the file is typically around half the size of JPEG, and it supports higher bit depth (10- and 12-bit) for smoother gradients. The tradeoff is reach: JPG opens on essentially everything, while HEIF is practically limited to Apple devices, Windows 11 with extensions, and Safari. Pick HEIF for an Apple photo library; pick PS to JPG when it has to open anywhere.

Does each PostScript page become a separate HEIF image?

Yes. A 10-page .ps produces 10 HEIF images, one per page, named by page index. Download them individually or grab the whole set as a ZIP. If you later need them back in a single document, use Merge Image to PDF.

What DPI should I choose for a PostScript page?

It depends on where the image will live. In our testing, a single-page letter-size .ps rendered at 150 DPI and the Very High preset produced a HEIF well under a megabyte that stayed crisp on a phone screen, while 300 DPI roughly quadrupled the pixel count for print-grade detail. Use 96–150 DPI for screen and chat, 300 DPI for general print, and 600 DPI only for archival masters — anything higher mostly inflates the file.

Is .ps and .eps handled the same way?

They're closely related — EPS (Encapsulated PostScript) is a single-page PostScript variant designed to be embedded in other documents. Both rasterize to HEIF the same way; if your file is .eps, use EPS to HEIF instead so the page is set up for the encapsulated format.

Is my PostScript file uploaded to a server, and how long is it kept?

Yes — rasterizing PostScript at print DPI is heavy work best handled server-side. Your file is uploaded over an encrypted connection, processed, and the raw and converted files are deleted automatically a few hours after conversion. There's no sign-up, no account, no watermark, and files are never shared or made public.
