Frequently Asked Questions

Why is 100KB the recommended target for resume and profile photos?▼
A 100KB image delivers near-perfect 1080p visual sharpness while keeping file sizes small enough to avoid corporate HR email and applicant tracking system (ATS) bounce limits.
Will compressing my portrait to 100KB alter facial colors?▼
No. Our in-memory HTML5 Canvas rendering preserves standard sRGB color profiles, preventing color shifts or washed-out skin tones.
Can I convert HEIC iPhone photos to 100KB JPG?▼
Yes! Modern browsers automatically convert uploaded HEIC snapshots, and our tool compresses them down to standard baseline JPEG strictly under 100KB.
Is there any watermark added to the compressed photo?▼
Never. ExactSizeImage is completely free with zero watermarks, zero hidden fees, and zero software installations.
