300 KB photo resize — FAQ
How do I resize a photo to 300 KB?
Upload your photo in the tool above — the 300 KB target is already set. The tool automatically lowers the JPG quality until the file is under 300 KB, keeping the photo as clear as possible, then lets you download it. Everything runs in your browser.
Will compressing to 300 KB reduce the photo quality?
Some quality is traded for the smaller size, but the tool keeps the image as sharp as it can while staying under 300 KB. For a passport-style headshot, 300 KB is usually enough to look clean on an application form.
Does this tool upload my photo to a server?
No. The photo is compressed locally in your browser using the Canvas API. Your image never leaves your device, so it stays completely private.
Why do forms ask for a photo under 300 KB?
Many government and exam portals cap the upload size to keep their servers light and uploads fast. If your photo is larger than the limit, the form rejects it — so it must be compressed to under 300 KB before uploading.
