Best File Format for Printing
For most print jobs the best file to send is a print-ready PDF created at the final size with bleed included. For single photos, a high-quality TIFF or a maximum-quality JPEG is usually accepted. The right choice depends on the product and your print service.
Format comparison
| Format | Best for | Notes |
|---|---|---|
| Documents, brochures, posters, anything with text and vector art | Preferred by most print services; embed fonts and images | |
| TIFF | Photographic prints, archival files | Lossless and large; ask the service before uploading very big files |
| JPEG (maximum quality) | Photos when PDF/TIFF are not accepted | Smallest file, but repeated saving adds artefacts |
| PNG | Web graphics and files with transparency | Not usually required for commercial print; convert to PDF or TIFF |
What "print-ready" means
- Final size matches the product, with bleed included on every edge.
- Images have enough pixels for the required DPI (check with the PPI calculator).
- Text is converted to outlines or the fonts are embedded.
- Colour mode follows the printer's instructions (see the RGB vs CMYK guide).
- The file opens correctly and matches the template they provided.
Frequently asked questions
Should I send PNG or JPEG to a print shop?
For photos, a maximum-quality JPEG is usually better than PNG because PNG files can be unnecessarily large without improving print quality. When in doubt, ask the shop - many prefer PDF or TIFF.
Does a bigger file always mean better print quality?
No. Print quality depends on pixel dimensions, sharpness and correct setup - not file size alone. A correctly prepared 5 MB PDF can print better than a 50 MB file with low-resolution embedded images.
What resolution should embedded images be in a print PDF?
At least 300 PPI for documents and close-up prints, and 150–200 PPI for large-format pieces. Lower resolution may pass for distant viewing but can look soft when inspected closely.
