Many online submission portals (such as university admissions, job boards, or visa agencies) place a strict file size cap of 50KB on profile photos or signatures.
Our binary quality search algorithm automatically loops the compression process in memory to find the highest possible quality setting that yields a file size below the limit.
Uploading identity documents, signatures, or personal passport photos to external servers carries severe identity theft and data leak risks. OptiConvert runs 100% locally in your browser to compress images offline.
If the original dimensions are extremely large, the compression engine may slightly scale down the width and height to successfully meet the strict 50KB file size constraint.
Yes. Since no files are uploaded to any server, your personal documents remain completely private on your own device.
