PostScript to TIFF Converter

Convert PostScript to TIFF: What This Tutorial Covers

This walk-through is for anyone holding a legacy .ps (PostScript) print stream who needs print-ready or archival raster pages instead. By the end you'll know which Conversion Quality (DPI) and Compression Type to pick, why a multi-page document comes back as a ZIP of one TIFF per page rather than a single stacked file, and when TIFF is the wrong target. PostScript and TIFF both grew up in prepress — PostScript as Adobe's 1984 page-description language for driving imagesetters and laser printers, TIFF as the bitmap that print and archival workflows hand around — so rasterizing one to the other is a natural pairing when you want fixed, high-resolution image pages.

How to Convert PostScript to TIFF

1. Upload Your PostScript File: Drag and drop your .ps file onto the page or click "+ Add Files". You can queue several files and convert them with the same settings.
2. Set the Conversion Quality (DPI): Open Advanced Options and pick a value under Conversion Quality. This is the resolution each vector page is rasterized at — 300 DPI is the default and the usual print/archival choice; drop to 150 DPI for smaller files or raise to 600/1200 DPI for fine line art.
3. Pick a Compression Type: Under Image Compression, choose how the TIFF is packed. LZW is the default and the most widely supported lossless option; Deflate (ZIP) is also lossless and safer for 16-bit pages; PackBits is a fast baseline option; None leaves the file uncompressed.
4. Convert and Download: Click "Convert" and download your TIFF. A multi-page .ps returns a ZIP of one TIFF per page. No sign-up, no watermark.

Walk-through: Choosing DPI and Compression

The two settings that actually change your output are Conversion Quality (DPI) and Compression Type. PostScript stores a page as vector drawing commands with no fixed resolution, so the converter has to "develop" it at a DPI you choose — that single number decides both the pixel dimensions and the sharpness of text and lines. Compression Type then decides how those pixels are stored inside the TIFF, with no effect on what the page looks like as long as you stay on a lossless method.

• For commercial print or imagesetter hand-off: keep 300 DPI (or 600 DPI for fine type) and LZW. This is the conventional prepress combination — lossless, broadly readable, and bit-for-bit faithful to the rendered page.
• For long-term archival of 16-bit pages: choose Deflate (ZIP). It is lossless like LZW but avoids a known quirk where LZW's dictionary approach can actually enlarge high-entropy 16-bit data.
• For maximum compatibility with old TIFF readers: PackBits is required of every baseline TIFF reader, so it opens essentially anywhere, at the cost of weaker compression on detailed pages.
• For on-screen review only: drop to 150 DPI to shrink the files; you lose detail you wouldn't see on a monitor anyway.

Common Errors and How to Fix Them

• "I got a ZIP, not one TIFF" — A document-to-TIFF conversion writes one TIFF image per page, and a multi-page .ps is bundled as a ZIP so nothing is lost. This converter does not stack the pages into a single multi-page TIFF. If you need every page inside one file, convert PS to PDF — PDF is the one-file page container here.
• "The TIFF won't open in my browser" — That is expected. Other than Safari, browsers do not natively display TIFF in web pages; it's a print and editing format, not a web format. Open it in an image editor or viewer, or convert PS to JPG for something that opens anywhere.
• "Text is blurry when I zoom in" — DPI was set too low for the detail you need. Re-run at 600 or 1200 DPI; the page is rasterized at render time, so a higher DPI captures finer line art and small type.
• "The file is huge" — Uncompressed or high-DPI TIFFs are large by nature. Switch Compression Type to LZW or Deflate, lower the DPI if the page is for screen, or compress the result with Compress TIFF.
• "My .ps won't render at all" — Some PostScript files reference fonts or resources that aren't embedded, or are actually corrupt print spool dumps. Try re-exporting the PostScript from its source application before converting.

When This Doesn't Work

If your .ps is a damaged print-spooler dump, references fonts that were never embedded, or relies on device-specific PostScript operators from an old RIP, rasterization can fail or substitute fonts. In those cases, route the file through PS to PDF first — PDF keeps the document as one scalable file with text and vectors intact, and you can rasterize from there if you still need images. For the identical conversion under the older three-letter file extension, see PS to TIF; the .tif and .tiff extensions are two spellings of the same format and produce identical output.

Frequently Asked Questions

Does a multi-page PostScript file become one multi-page TIFF?

No. This conversion renders one TIFF image per page, and a multi-page .ps is delivered as a ZIP containing those separate TIFFs rather than a single stacked file. The TIFF format itself can hold multiple images, but this document-to-image pipeline writes them out per page so none are lost. If you specifically need every page kept together in a single file, PS to PDF is the one-file container to use.

What DPI and Compression Type should I use for print or archival?

For most print and archival work, 300 DPI with LZW compression is the standard pairing — LZW is lossless and the most broadly supported TIFF compression, so the file stays bit-for-bit faithful and opens in virtually every prepress and editing tool. Raise the DPI to 600 or 1200 for fine line art, and switch to Deflate (ZIP) if you're working with 16-bit pages, where it compresses more reliably than LZW.

Is the TIFF output lossless?

It can be, and by default it is. LZW, Deflate, PackBits, and None are all lossless, so the stored pixels exactly match the rendered page — the only quality limit is the DPI you choose, because rasterizing a vector page to a fixed pixel grid is itself a one-way step. The JPEG compression option inside TIFF is the exception: it is lossy and trades fidelity for a smaller file.

Why can't I open the TIFF in my web browser?

TIFF was built for print, archival, and precision editing, not the web. Other than Safari, mainstream browsers do not natively render TIFF in a web page, so it usually opens in a desktop image editor or viewer rather than a browser tab. If you need a page image that opens anywhere — chat, slides, email — convert PS to JPG instead.

Does converting keep the PostScript vectors scalable?

No. PostScript describes pages as vector drawing commands, but rendering to TIFF bakes them into a fixed grid of pixels at your chosen DPI, so the result no longer scales cleanly beyond that resolution. If you need to keep crisp, infinitely scalable text and vectors in one document, PS to PDF is the faithful conversion — PDF is a direct descendant of PostScript and preserves the vector pages exactly.

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 document rendered at 300 DPI with LZW produced a clean, print-sharp TIFF with text edges that stayed crisp at full zoom.
