Fast, secure PS to PNG conversion. No registration required.
Setup: PS is a document format oriented around a particular office suite or publishing pipeline. Goal: an interchangeable PNG. Need a PNG copy of a PS file for a workflow that refuses the original? This tool picks the right converter automatically (ghostscript for this particular pair), re-renders the content and returns a ready-to-use PNG. No desktop apps to install, no command-line flags to memorise. Context: PS is a document format oriented around a particular office suite or publishing pipeline. PNG is the lossless image standard with alpha-channel transparency and deflate compression.
PostScript
Source formatPostScript is a page description language used in desktop publishing and professional printing.
PNG Image
Target formatPNG is a lossless image format that supports transparency. It is ideal for graphics, logos, screenshots, and any image where preserving exact pixel data is important.
Why convert PS to PNG
PNG is better supported than PS in the workflow you are targeting. Converting trades any niche advantages of PS for broad compatibility, and the conversion itself is fast because the two formats share the same conceptual content.
HOW TO CONVERT
PS → PNG
Upload the PS
Drop your file into the browser uploader. We transfer over HTTPS and queue the conversion.
Convert through ghostscript
Our ghostscript-based pipeline reads the PS, applies the right decoder and emits a faithful PNG.
Download the PNG
Grab the result when it lands. Both files delete automatically within two hours — nothing lingers on our servers.
Common Use Cases
Share across platforms
Send PNG files to anyone without worrying about whether they have the right software for PS.
Embed in documents
Drop PNG output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
PNG often produces smaller files than PS for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
PS vs PNG — Strengths and limitations
What each format does best, and where it falls short.
PS Strengths
- Device-independent — same file prints identically on any PostScript printer.
- Vector-based at heart; rasterization happens at the printer's DPI.
- Programmable — dynamic pages, variable data, and procedural art all possible.
- Legacy standard in academic and print pipelines.
Limitations
- Turing-complete = security hole; malicious PS files can hang printers or exploit vulnerabilities.
- Not a display format; browsers cannot render PostScript without conversion.
- Mostly superseded by PDF (which is PostScript's sandboxed, declarative descendant).
PNG Strengths
- Lossless compression — every save preserves the original pixels perfectly.
- Full 8-bit alpha channel for smooth transparency.
- Excellent for text, UI screenshots, logos, and line art.
- Royalty-free and an ISO standard (ISO/IEC 15948).
- Supports 16-bit color depth for high-fidelity work.
Limitations
- Much larger than JPEG for photographs (no perceptual compression).
- No native animation in most software (APNG support is inconsistent).
- No CMYK support — web and screen only, not print.

- Print-ready illustration 5–50 MB
Quality & Compatibility
The conversion preserves the important content and lets you control quality trade-offs through Advanced options. Lossless paths produce PNG output that matches the PS content exactly; lossy paths re-encode at transparent defaults unless you request otherwise. Metadata transfers where both formats support it.
Tips for Best Results
- Always keep the original PS file alongside the PNG — you may need it later if requirements change.
- Check a small sample of the PNG in its destination application before batch-converting a large archive.
- For recurring conversions, the REST API on paid plans automates the whole pipeline programmatically.
Frequently Asked Questions
Yes. The free tier accepts files up to 25 MB without registration, email capture or watermarks; paid plans go up to 2 GB. Paid plans raise the size cap, enable batch conversions and provide a REST API for automation, but nothing on the free tier is quality-limited — the output is exactly the same as on any paid plan.
Uploads run over HTTPS, files are processed in isolated containers, and both the source PS and the PNG output are auto-deleted within two hours. No account is required, file contents are never logged, and KaijuConverter does not use uploads for AI training. The paid plan adds a signable data-processing agreement for regulated workflows.
Most files finish in well under a minute. Small images and documents are typically ready in a few seconds; large video or audio files scale roughly with duration. Upload speed from your network is usually the dominant factor, not server time.
