A local-first checklist for resizing images
Most image upload problems come from confusing dimensions with file size. Width and height control the canvas; KB measures the encoded file. A reliable workflow solves them separately.
First, resize to the required pixel dimensions while preserving aspect ratio unless a fixed frame is mandatory. Next, encode the result and measure the real bytes. For JPEG or WebP, adjust quality iteratively instead of assuming one percentage will always hit the same KB target.
Sensitive application photos and signatures are good candidates for local processing because the original file does not need to be sent to a remote image server.
IncreaseImages is a free browser-local tool for increasing image dimensions or targeting a KB range: https://increaseimages.org/
Before download, verify the final width and height, check the measured file size, inspect text and edges at 100% zoom, and keep the source file as a fallback.
