Meet the pixel requirements for ID and passport pictures
Online visa and ID applications often reject photos below a minimum resolution. If your passport photo is sharp but too small, upscaling it can meet the pixel requirement without retaking it.
Upscaling ID photos the careful way
Official photos must show your real appearance, so use conservative settings: Lanczos or bicubic, low sharpness and no colour boost. These methods add pixels mathematically rather than inventing facial detail, which keeps the passport photo faithful to the original.
Check the official rules
Each authority sets its own size, background and file-type rules; upscale to the required dimensions and export JPG if the form demands it.
Privacy
A face photo is personal data. Processing locally means it is never uploaded to a third-party server.
