Tips for Best Results
Start with a high-quality source photo — compressing an already-blurry image produces poor results. Crop tightly around the subject first. JPG output produces the smallest files. Check portal format requirements (most need JPG/JPEG).
Frequently Asked Questions
How do I reduce an image to exactly 100KB?
Upload your image, select 100KB target, click Compress. Our algorithm automatically adjusts quality to hit the target while keeping maximum visual quality.
Will the quality be good enough for my application?
Yes. Our compression keeps faces and text clear even at small sizes. For form uploads, quality is more than sufficient.
Can I resize a phone photo?
Yes. Upload directly from your phone gallery. HEIC photos (iPhone) are automatically converted to JPG. Also try HEIC to JPG.
What if the portal needs specific dimensions (3.5×4.5 cm)?
Use passport photo converter for dimensions first, then compress to target size here.
