When 5 MB is the rule
A 5 MB cap is a different beast from the tight limits on ID portals. It exists to stop truly massive files, not to make photos tiny. You’ll find it on:
- Online photo print services that cap each upload
- Application and grant portals that accept supporting photos
- Photo competitions asking for high-quality entries
- Some cloud forms and CRMs used by businesses
Most 12 MP iPhone HEICs would pass on size already, but these services usually want JPG. Convert at very high quality, though, and some photos land just over 5 MB. That’s where this page comes in.
Built for quality first
We start at quality 92, which is excellent for prints and archiving, and only step down if a photo won’t fit. Dimensions are left alone unless quality has already dropped as far as it sensibly can (about 55), which, at 5 MB, is very rare indeed.
Getting prints that look like your phone screen
Pixels matter more than megabytes
A print’s sharpness comes from its pixel dimensions. Because this target almost always keeps the full resolution of your photo, you get the most detail your camera captured.
Ask your lab about colour
iPhones capture in Display P3. We keep that profile embedded, which colour-managed software handles well. Some print labs prefer sRGB files. If yours does, set Colour to sRGB before you drop your photos in.
Check the crop
Print sizes have their own aspect ratios. If a print shape differs from your photo’s, the lab may crop it. Use Crop HEIC with a preset like 3:2 or 4:3 to choose the framing yourself.
For more on paper sizes and lab settings, see Convert HEIC for printing or our guide on how to print HEIC photos.
Compared with smaller targets
| Target | Typical result for a 12 MP photo |
|---|---|
| 1 MB | Full or near-full size, good quality |
| 2 MB | Full size, high quality |
| 5 MB | Full size, very high quality |
Large files, local processing
Big photos mean big uploads elsewhere, but not here. Your device does all the work, so a batch of 48 MP shots costs you no upload time at all. On iPhone and iPad, Safari may scale very large photos to around 16 MP because of its canvas limits.
