Supports: XCF
.xcf files or click "Add Files". Batch is supported — drop in several XCF files and each converts in parallel, then download them together as a ZIP.XCF (short for eXperimental Computing Facility, named after the UC Berkeley lab where GIMP began) is the native project format of GIMP, the free image editor, introduced alongside GIMP 1.0 in 1998. It is the GIMP equivalent of Photoshop's PSD: a single .xcf stores the entire editing state — every layer with its opacity and blending mode, layer masks, channels, paths, guides, and the image's color profile — losslessly, so you can reopen the project and resume exactly where you left off. Modern XCF (GIMP 2.10 and later) also supports 8-bit, 16-bit, and 32-bit floating-point precision per channel.
The catch is compatibility. XCF is essentially a working format, not a delivery format: almost nothing outside GIMP opens it. A handful of editors read it — Krita, the browser-based Photopea, and ImageMagick among them — but most websites, email clients, office apps, photo viewers, and phones can't display an XCF at all. Converting turns that editing master into a file the rest of the world can open. Common reasons people convert an XCF:
.xcf, and most upload forms reject it. Export to PNG when you need to keep transparency or sharp edges (logos, UI mockups, screenshots), or to JPG when it's a photo and you want the smallest file for email and the web.One honest caveat: every one of these targets is a flat image. Converting an XCF flattens its layers, masks, and channels down to a single rendered picture — the editability is baked in and can't be recovered from the output. Keep your original .xcf as the editing master and treat the converted file as a deliverable.
| Target format | Compression | Transparency | Best for |
|---|---|---|---|
| PNG | Lossless | Yes (full alpha) | Sharing layered work, logos, UI mockups, screenshots |
| JPG / JPEG | Lossy | No (flattens onto background) | Photos, email, web uploads where small size matters |
| Container | Yes (in PDF) | Multi-page documents, proofs, client deliverables | |
| TIFF | Lossless or LZW | Yes | Print masters and archives; large files, openly documented |
| WebP | Lossy or lossless | Yes | Modern web galleries; ~25-35% smaller than PNG/JPG at similar quality |
| BMP | Uncompressed | No | Legacy Windows pipelines that need raw pixels; very large files |
Not much, which is the usual reason to convert one. XCF is GIMP's native project format, so GIMP opens it fully. A few other editors read it with varying fidelity — Krita, the browser-based Photopea, and the ImageMagick command-line tool among them — but most photo viewers, office apps, web upload forms, and phones can't display an XCF at all. If you just need someone to see the image, convert it to PNG or JPG; if you need to keep editing it, open it in GIMP and keep the .xcf master.
Yes. PNG, JPG, TIFF, WebP, and the other targets here are flat image formats — they store a single rendered picture, not a stack of editable layers. Converting an XCF merges all visible layers, masks, and channels into that one image, and the layer structure can't be recovered from the output afterward. This is fine for a finished deliverable, but it means the converted file is not a substitute for your project file. Always keep the original .xcf if you might edit it again.
PNG, WebP, TIFF, and AVIF all preserve the alpha channel, so transparent areas in your GIMP project stay transparent. PNG is the safest, most widely supported choice for transparent graphics like logos and UI elements. JPG and BMP do not support transparency — converting to either flattens transparent regions onto a solid background color, which the converter lets you pick for JPG output.
No. PNG is a lossless format, so an XCF exported to PNG reproduces the flattened image pixel-for-pixel with no compression artifacts. The only thing "lost" is the layer structure, which is inherent to moving from an editable project to a flat image — the visible pixels are identical. If you instead pick JPG or a lossy WebP, the Quality Preset controls how much detail is traded for a smaller file; "Very High (Recommended)" keeps it visually indistinguishable in most cases.
It depends on the content. For graphics with transparency, sharp edges, or text — logos, icons, UI mockups — convert to PNG, which stays crisp and keeps the alpha channel. For photographs or painted artwork where file size matters more than perfect edges, JPG is smaller and universally accepted. For a multi-page document or a client proof, PDF wraps everything into one file that opens anywhere. In our testing, a 1920×1080 GIMP project with several layers exported to a roughly 600 KB PNG and a roughly 180 KB JPG at the "Very High" preset.
Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, and they are never shared or made public. Because conversion runs on our servers rather than in the page, there's no per-file software install, and batch jobs of multiple XCF files convert in parallel and download together as one ZIP.
