What happens when you convert PDF to QOI?
Lossless sample storage
QOI preserves 8-bit RGB/RGBA samples losslessly. Reducing 16-bit data or discarding profiles and metadata before encoding is outside that guarantee. QOI can store its supported image samples without lossy compression. This applies after rendering and sample conversion: it does not guarantee preservation of source precision, colour space or document structure, and cannot undo earlier losses.

Good choice when
- QOI fits your delivery use: Application assets & simple decoding.
- You need a raster preview of a document page.
- You need a transparency-capable destination and will check its supported variant.
- You need lossless storage of the rendered samples supported by QOI.
Probably not when
- Selectable text, vector objects or document navigation must remain.
- You assume format-level alpha support guarantees matching transparent edges.
- You expect lossless encoding to restore lost details or editing structure.
- You require identical samples without a defined colour and precision policy.
PDF to QOI conversion details
- Page rendering
- One page is converted (default: page 1). Choose another page in Advanced options.
- Transparency representation
- The implemented target supports alpha. Display-pixel processing can round translucent samples; archival sample equality is not promised.
- Lossless sample storage
- QOI preserves 8-bit RGB/RGBA samples losslessly. Reducing 16-bit data or discarding profiles and metadata before encoding is outside that guarantee. QOI can store its supported image samples without lossy compression. This applies after rendering and sample conversion: it does not guarantee preservation of source precision, colour space or document structure, and cannot undo earlier losses.
- Sample precision & colour
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
- Metadata & colour
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
- Compression
- PDF: Depends on variant → QOI: Lossless PDF: PDF has no single compression quality. Different streams may use lossless or lossy filters; page rasterization can remove document structure even when the resulting pixels are encoded losslessly. QOI: QOI preserves 8-bit RGB/RGBA samples losslessly. Reducing 16-bit data or discarding profiles and metadata before encoding is outside that guarantee.
- Transparency
- Transparency is replaced with white by default. Change the background in Advanced options.
- Colour depth
- QOI: 8 bits/sample
- Multiple images
- PDF: Page tree
- Vector graphics
- PDF: Paths & text on pages

- Metadata
- Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.

Does lossless output mean an unchanged source?
QOI preserves 8-bit RGB/RGBA samples losslessly. Reducing 16-bit data or discarding profiles and metadata before encoding is outside that guarantee. QOI can store its supported image samples without lossy compression. This applies after rendering and sample conversion: it does not guarantee preservation of source precision, colour space or document structure, and cannot undo earlier losses.
Are bit depth and colour values guaranteed to match?
Pixel conversion only. Original EXIF, GPS, XMP and ICC profiles are not copied; processing uses 8-bit display pixels.
Will metadata and colour profiles be retained?
