Resolution, pixels and megapixels
Resolution in everyday use means pixel count. A 4000 × 3000 photo is 12 megapixels. Increasing resolution means resampling to more pixels; whether those pixels carry more visible detail depends on the method — classical filters keep the picture smooth, the AI engine adds reconstructed detail.
Megapixel targets keep the aspect ratio and give a predictable file and print size. The readout also shows the size at 300 DPI, the usual figure for photo prints.
Resolution for print
As a guide, at 300 DPI:
- 2 MP (1732 × 1155) ≈ 5.8 × 3.9 in (14.7 × 9.8 cm)
- 8 MP (3464 × 2309) ≈ 11.5 × 7.7 in (29.3 × 19.6 cm)
- 12 MP (4243 × 2828) ≈ 14.1 × 9.4 in (35.9 × 23.9 cm)
- 24 MP (6000 × 4000) = 20 × 13.3 in (50.8 × 33.9 cm)
Questions
Is increasing resolution the same as increasing DPI?
No. Resolution is pixel count. DPI is a label in the file that says how many of those pixels to print per inch. Changing DPI alone (see Change image DPI) does not add pixels; increasing resolution does.
What is the highest resolution I can make?
Up to 100 megapixels with classical methods; AI results are limited to 48 MP on desktops and 16 MP on phones to stay within browser memory.
Why does my file get so much bigger?
File size grows roughly with pixel count. JPEG or WebP at quality 85–92 keeps big results manageable; the readout estimates the size before you scale and shows the exact size after.
Is my picture uploaded anywhere?
No. Decoding, scaling and encoding all run in this browser tab, and the scaling engine runs in a Web Worker with no network code in it. The only download the site can make for you is an AI model file, and only after you press the button that names its size — that request contains no picture.
