Fast, secure XCF to PDF conversion. No registration required.
Here is the short version — XCF is GIMP's native editing format preserving layers, masks and paths. Hence the need for PDF. A PDF containing a XCF is the universal envelope for anything visual that needs to travel through a document-only pipeline. Tax portals, HR systems, expense tools, academic submission sites all speak PDF first. Keep in mind XCF is GIMP's native editing format preserving layers, masks and paths. And remember that PDF is Adobe's Portable Document Format, the fixed-layout standard for shareable documents.
GIMP Image
Source formatXCF is the native image format for GIMP, supporting layers, channels, and paths.
PDF Document
Target formatPDF is the universal standard for sharing documents with consistent formatting across all devices and operating systems. It preserves fonts, images, and layout exactly as intended by the author.
Why convert XCF to PDF
Printing a PDF is predictable; printing a XCF from a browser depends on the browser. For archival and paper distribution, producing a PDF up front removes half the failure modes.
HOW TO CONVERT
XCF → PDF
Start the job
Upload XCF; the pipeline reads pixel dimensions, colour profile and orientation.
Layout the page
The image is centred or stretched to the configured page size (A4 by default); DPI is preserved for print fidelity.
Save the result
Download the PDF — or preview it in the browser before saving.
Common Use Cases
Share across platforms
Send PDF files to anyone without worrying about whether they have the right software for XCF.
Embed in documents
Drop PDF output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
PDF often produces smaller files than XCF 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.
XCF vs PDF — Strengths and limitations
What each format does best, and where it falls short.
XCF Strengths
- Native GIMP format — full fidelity for every tool and feature.
- Open, documented spec.
- Supports layers, channels, paths, masks, guides, selections.
- Gzip-compressed variant keeps files compact.
- Backward-compatible since 1995.
Limitations
- Limited ecosystem — Photoshop, Illustrator, and browsers don't open XCF.
- No native CMYK support (a longstanding GIMP limitation).
- 32-bit precision only since GIMP 3.0 (2025).
PDF Strengths
- Pixel-perfect fidelity across operating systems, browsers, and printers.
- Embeds fonts, so documents render identically without the reader having them installed.
- Supports digital signatures, encryption, and redaction for legal workflows.
- ISO-standardized (ISO 32000) with multiple validated subsets (PDF/A, PDF/X, PDF/UA).
- Supports both vector and raster content, keeping line art crisp at any zoom level.
Limitations
- Editing is difficult — the format is optimized for display, not mutation.
- Text extraction can scramble reading order in multi-column layouts.
- File sizes balloon quickly when embedding high-resolution images or fonts.

XCF vs PDF — Typical file sizes
Approximate file sizes for common scenarios.
XCF
- Simple 2-layer edit 500 KB - 3 MB
- Website mockup with 20 layers 10-50 MB
- High-res photo composite 100-400 MB
- 1-page text-only memo 50–150 KB
- 10-page report with images 500 KB – 2 MB
- Scanned document (per page) 100 KB – 1 MB
- Full-color magazine (48 pages) 10–40 MB
Quality & Compatibility
Colour fidelity depends on the PDF's colour-management features. PDF embeds ICC profiles so print houses receive the exact colours; older document formats may clip wide-gamut XCF material to sRGB.
Tips for Best Results
- When the XCF contains sensitive information (IDs, bank statements), convert to PDF and then run the PDF through a redaction tool rather than editing the original image.
- For batch operations, upload a ZIP of many XCF images and the pipeline will emit one PDF per image (or a single combined PDF if you toggle "merge" in Advanced).
- Set Title and Author in Advanced before download so your document management system indexes the PDF correctly.
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.
Minimally. When the image encoding carries directly into the PDF (JPEG into PDF for example), pixels are stream-copied and quality is bit-exact. When re-encoding is required, we use high-quality defaults that are visually indistinguishable from the source on typical viewing conditions.
Uploads run over HTTPS, files are processed in isolated containers, and both the source XCF and the PDF 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.
Yes. Upload multiple images (or a ZIP) and the pipeline produces a multi-page PDF with one image per page, ordered by filename. Advanced options control page size, orientation per page and whether captions are inserted.
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.
A4 portrait by default — the global mainstream. Switch to Letter or any custom dimensions in Advanced. You can also select "match image" so the PDF page size tracks the XCF aspect ratio exactly, eliminating white margins for custom printing.
