Create a practical frame-ratio bundle
Different frames need different image shapes. A 2:3 file fits proportional sizes such as 4 × 6 and 12 × 18 inches, while an 8 × 10 frame uses 4:5. Simply stretching one file into every frame would distort the artwork. This tool either crops the source to each shape or fits the full image inside it with borders.
The standard set uses 12 × 18 inches for 2:3, 12 × 16 for 3:4, 8 × 10 for 4:5, A4 for ISO A, 11 × 14 for 11:14 and 12 × 12 for square. Small and large sets provide alternative intended dimensions, all listed before download. Landscape swaps width and height; the source artwork itself is not rotated.
ISO paper dimensions are rounded to whole millimetres, so their ratios vary slightly between A5, A4 and A3. Review the selected file against its intended sheet instead of assuming every ISO size is mathematically identical. A proportional file can fit smaller matching frames, but its available print resolution changes with the chosen physical size.
Inspect crops before exporting
The crop-box view shows which source area is retained. Horizontal positioning appears when a target ratio removes material from the left or right; vertical positioning appears when it removes the top or bottom. Each ratio keeps its own position, so a subject can be framed differently for a narrow poster and a square.
The Print file view previews the exported composition at a reduced screen size. In full-artwork mode, the entire source is centred and extra space becomes a border. JPG fills transparent regions with the selected background. PNG can retain transparency or use the same background colour.
No artwork is generated, no subject is reconstructed and no missing edge is invented. Cropping removes visible source area from the exported copy. Your original remains unchanged, and you can switch to borders whenever preserving all of the composition matters.
Pixel density and enlargement are separate decisions
The target PPI describes a requested pixel count at the intended print dimensions. With pixel enlargement off, output dimensions are reduced when the source cannot provide enough pixels. Every export is also capped at 16 million pixels and 8,192 pixels per side for browser memory safety. The interface reports the resulting dimensions before export.
Allow pixel enlargement uses ordinary resampling. It can produce more output pixels, but it does not recover authentic detail. The source-detail estimate therefore stays visible even when the output reaches the requested pixel density. Neither estimate can determine whether the source was already blurry or whether it will suit a particular printer or viewing distance.
Density metadata is written from the actual output PPI at the intended size, rounded to a positive whole number. A smaller source-limited file is not silently labelled at the requested 300 PPI. The guide records exact output density, the source-detail estimate and the file’s physical dimensions at the selected target. Set the intended physical size explicitly when printing because density tags are rounded.
The ZIP image payload is limited to 96 MB. Use fewer ratios, JPG encoding or a smaller size set if a pack becomes too large. Browser canvas export can change embedded colour-profile handling; bleed, colour accuracy, printer settings and marketplace acceptance are not validated. Use PNG Print Checker for alpha-channel inspection or DPI Converter when only a metadata tag needs changing.
