Frequently asked questions
Can I resize my signature to 20 KB or 50 KB?
Yes. Enter 20 or 50 as the maximum KB. The tool attempts to create an output within your limit. Highly detailed images or very small limits may prevent an acceptable result.
Does this website save my photograph or signature?
No. The application processes images using browser canvas APIs. It does not send image data to a server or retain uploaded files. Files remain on your device unless you choose to download them.
Which dimensions should I use for a government exam form?
Use only the image dimensions, file type and file-size limit specified in the official application instructions. Presets in this tool are examples, not official requirements for any particular examination.
Can PNG files always be reduced to an exact KB target?
No. PNG compression is lossless and browser encoders have limited size controls. If a PNG remains too large, consider JPG or WebP only if your application permits those formats.
Can I resize scanned certificates?
Yes, use the Document Image Reducer tab for JPG, PNG, BMP or WebP scans. This version does not accept PDF uploads.
