ABOUT photo printing
Dimensions
Most modern smartphones and cameras shoot at a different aspect ratio than the standard 10×15 cm format. This means the edges of your photo may be slightly cropped when printing, so the image fills the frame without white borders.
The 10×15 cm format corresponds to a 2:3 aspect ratio.
If your photo has a different ratio (e.g. 4:3 from a phone camera), the editor will crop the edges of the photo — we recommend reviewing and adjusting your photos before ordering.
For the 10×15 cm format, we recommend using 2:3 ratio photos with a resolution higher than 1200×1800 px.
Photo Print Specifications

We offer convenient online photo printing, making it easy to turn your digital memories into real photographs.
We use digital printing — a modern technology that allows photos to be printed quickly and accurately directly from your file. Unlike a traditional photo lab, digital printing requires no lengthy chemical processes, so you receive your photos faster. To ensure the best possible quality, every photo is automatically processed before printing — we adjust the colours, sharpness and brightness to meet printing standards. This means that even photos taken with a standard phone camera will achieve photo lab quality on paper.
Automatic Photo Enhancement
Our system automatically analyses the sharpness, contrast and colour richness of each photo and subtly improves image quality where needed. When ordering photo prints in our editor, automatic photo enhancement is enabled by default.
How do we ensure accurate colours in print?
Every photo is automatically processed before printing — the colour balance is adjusted to meet printing standards. This reduces the difference between what you see on screen and what you receive on paper.
Screens and paper reproduce images differently
Screens emit light — paper reflects it
Your phone or computer screen produces its own light — this gives the image brightness, rich colours and contrast. Paper only reflects ambient light, so the same image may appear slightly less vivid, especially in low lighting. In good natural light, a print often looks even better than on screen.
The colour systems are different
Screens use the RGB colour system — colours are created from red, green and blue light. Printing uses the CMYK system — colours are created by mixing inks. Some very bright or saturated screen colours physically cannot be reproduced exactly in ink — so they may appear slightly different in print.
Frequently asked question about photo printing
The 10×15 cm format corresponds to a 2:3 aspect ratio.
If your photo has a different ratio (e.g. 4:3 from a phone camera), the editor will crop the edges.
- Minimum resolution — 1200×1800 px.
- Optimal — 1800×2700 px.
- Ideal — 2400×3600 px.
Before ordering photo prints, we recommend checking that your photos look bright enough on your device screen and that you are happy with their exposure. It is important to know that the image you see on screen may differ from the final print.
Please pay attention to a few important points:
- If your phone or computer screen brightness is set very high, photos may appear lighter than they actually are. We recommend setting your screen to a medium brightness level.
- Photos always look brighter on screen than when printed, because screens are backlit from the inside, while physical prints are not. For this reason, photo prints will naturally appear slightly darker than what you see on your phone or computer.
Your uploaded photos and edited layout are stored only during the active session. If you close the browser, turn off your phone or log out without completing your order — the uploaded data will be deleted and you will need to start again. We recommend completing your order in one session.
If the photo was taken with a phone after 2015 — the quality will be excellent. If the photo looks sharp on your phone screen, it will look sharp on paper too.
Almost all modern phones produce photos that exceed the minimum requirements:
- iPhone 12 and newer — 12 MP = ~4032 × 3024 px
- Samsung Galaxy S21+ — 12–108 MP
- Mid-range phones from 8 MP — ~3264 × 2448 px
- An 8 MP phone already provides more than sufficient resolution for the 10×15 format.
Screenshots — screen resolution is typically 72–96 DPI, while printing requires at least 150+ DPI. A screenshot from Instagram or Facebook will significantly reduce print quality.
Heavily cropped photos — if you zoom in and crop a photo significantly, you reduce its resolution. Automatic enhancement can help, but only up to a point. Compressed photos — WhatsApp and Messenger automatically compress photos.
We recommend sending the original or uploading directly from your phone gallery.
We do not recommend using photos from social media due to poor resolution and quality.
Facebook, Instagram and WhatsApp automatically compress every uploaded photo. This means that an original file of e.g. 4032×3024 px becomes ~1080×1350 px or less after being uploaded to Instagram. When you download the photo, you no longer have the original — only a compressed copy. This is why the ZOOMBOOK editor will show a "low resolution" warning.

You can upload photos in JPG, PNG and HEIC formats.
There is no set limit on the number of photos you can upload — you can upload as many as you need.
However, if you plan to upload more than 50–100 photos, we recommend doing so in batches.
A large number of files at once may take several minutes — depending on your internet speed and device. Uploading in batches will help you avoid long waiting times and reduce the risk of having to start over due to a screen timeout or lost connection.
This is related to the aspect ratio of your photo and the 10×15 cm format.
Modern phones shoot in different formats — most commonly 4:3 or 16:9. However, the 10×15 cm format has its own aspect ratio — 2:3. If your photo was taken in a different ratio, the system automatically adjusts the image to fit the format, and the edges may be slightly cropped.
- Photo taken in 4:3 format (common phone setting) — the sides or top/bottom will be cropped
- Photo taken in 16:9 format (panoramic, screenshot) — significantly more will be cropped
- Photo taken in 2:3 format — will fit perfectly, no cropping
How to avoid this:
While editing your photo during the ordering process, you can choose which part of the image will be printed — simply drag the frame to your preferred position.
Upload your photo to our editor, adjust and rotate if needed, set the quantity and order.
