Pick a JPG, PNG or WebP photo from your phone or computer.
Tap a ready size such as Passport 3.5×4.5 cm or 2×2 inch, or type your own width and height in cm, mm, inch or pixels.
Keep 300 DPI for printing (200 DPI is common for online forms). Drag the crop box so the face sits in the centre — it always keeps the right shape.
If the form says 'maximum 50 KB', choose 50 KB. Then tap Resize Photo and download.
Photo Resizer changes a photo to an exact physical size — like 3.5 × 4.5 cm for a passport photo or 2 × 2 inch for a US visa — or to exact pixels such as 200 × 230 px for exam forms. It converts cm, mm and inches to pixels using the DPI you choose, crops without stretching the face, writes the DPI into the file and can keep the file under a KB limit.
At 300 DPI it is 413 × 531 pixels; at 200 DPI it is 276 × 354 pixels. The tool does this conversion for you and shows the pixel size before you download.
Photo Resizer is for a single photo that must match a print size or form size (cm, inch, DPI, KB). Image Resizer changes the pixel size of many images at once — for websites, social media or emails.
Use 300 DPI if you will print the photo. For online forms that give the size in pixels, the DPI does not change how the photo looks — 200 DPI is a common choice.
Yes. Choose the size first, then pick the KB limit. If the limit is very small, lower the DPI so there are fewer pixels to fit in.
No. The tool runs entirely in your browser, so your file never leaves your device and nothing is stored on our side.
