About Reduce Photo Size to 300 KB
Need a photo under 300 KB? Many application forms, portals and e-mail systems reject files above a size limit. This tool searches for the highest JPG quality that fits under 300 KB and, if that is not enough, reduces the pixel dimensions step by step. Detail stays high, which is mostly useful for e-mail attachments and portals with generous limits.
FAQ
Will the file really end up under 300 KB?
In almost all cases yes. Very large or noisy photos may lose resolution to reach the target; the result list shows the final size of every file.
Are my files uploaded to a server?
No. Everything runs in your browser; your files and text never leave your device.
Is it free? Do I need an account?
The tool is free and needs no registration.
Does it work on a phone?
Yes, in modern desktop and mobile browsers; large files depend on your device power.
