FAQ

Will compressing photos below 100KB make them blurry?

No. The compression algorithm automatically calculates the optimal balance between pixel dimensions and encoding quality to ensure portraits remain crisp.

Why do application portals frequently enforce a 100KB maximum size?

Government portals, exam registrations, and visa websites enforce strict file size caps like 100KB to reduce database strain and expedite bulk page loading.

Is it safe to compress confidential ID photos with this tool?

Yes, completely safe. TrueFree Tools performs all image re-encoding on your device using client-side JavaScript. Photos are never uploaded to any server.
