Frequently Asked Questions
How do I resize my signature to under 10 KB or 20 KB?
Upload a clear photo of your handwritten signature on white paper. Click the Signature: ≤ 10 KB preset. LocalDoc automatically resamples it to standard signature dimensions (approx 140 × 60 px) and compresses the file size down to 8-10 KB ready for instant upload.
How do I resize a passport photo to under 20 KB without making it blurry?
Select the Photo: ≤ 20 KB (3.5 × 4.5 cm) preset. The tool applies high-quality bicubic downsampling and runs a logarithmic binary search to discover the highest-quality JPEG compression table that fits under 20 KB.
Why do online recruitment portals reject photos over 20 KB or 50 KB?
Civil service and exam servers receive millions of applications in short windows. Requiring photos under 20 KB and signatures under 10 KB prevents database overloading and speeds up candidate identity verification at exam centers.
Is my signature or photo saved anywhere?
Never. LocalDoc runs entirely in client-side volatile RAM using HTML5 Canvas. Your signature and photos never touch any cloud server or database.
