This page opens with Target size at 50 KB, the format set to JPG, and Maximum size at 600 × 600 pixels, the kind of box an ID photo, profile picture or scanned signature is uploaded in. Change the box to the dimensions your form names, or set it back to Original dimensions.
Why the pixel size comes first
A 50 KB budget is small for a full phone photo: a 12-megapixel picture would have less than one bit per pixel to spend, which is not enough for a clean JPG. The same 50 KB spread over a 600-pixel photo gives the encoder over a bit per pixel, which is enough for skin, hair and small text to stay sharp. So the page starts by fitting the picture into 600 × 600 (keeping its proportions, never enlarging it), and only then searches for the highest JPG quality under 50,000 bytes.
If your form says, for example, 200 × 230 pixels or 3.5 × 4.5 cm at a given DPI, choose Custom width × height and enter the pixel size. To turn centimeters into pixels, multiply by the DPI and divide by 2.54: 3.5 cm at 300 DPI is 413 pixels.
When a minimum applies
Many application portals publish a window rather than a single cap, such as “20 KB to 50 KB” for a photo. A small, plain picture can land below the minimum, because the tool never spends bytes it doesn’t need. The row shows the exact size; if it’s too small, switch to the Quality tab and raise the slider, or allow more pixels.
Check before you upload
- Look at the eyes and the edges of the hair in the compare view at 100%: blocky squares there mean the budget is too tight for the dimensions, so choose a smaller box.
- Crop to the head and shoulders before compressing; background uses bytes too.
- Keep the file name simple (letters, numbers and dashes). Some portals reject names with spaces or accents, and the downloaded file is named after your original with “-compressed” added.
