FAQ

Frequently asked questions

Some portals set a more generous signature limit of 50KB, which allows a higher-resolution scan. If your form specifies 50KB, use this size; if it asks for less, use the 20KB or 10KB tool.

No. We never store, share or look at your images — every file is discarded the moment processing finishes and nothing is saved. That makes it safe even for sensitive documents like passports, ID cards and bank statements.
