Practical advice for getting useful results from image and text tools, with clear steps and honest limits.

How to decode a Base64 image safely

Identify an image data URI, decode it to a real file, choose an export format and diagnose invalid or unsupported input.

Remove whitespace, blank rows and duplicates in the right order, then prepare a list for another app without uploading its contents.

Choose suitable source photos, tune color tolerance and edge feathering, and inspect a transparent PNG for halos or missing subject detail.

Frame a square image for profiles and product grids without stretching the subject or cutting away important detail.

Compare image formats by subject, transparency, editing needs and delivery context, then choose an export without losing information by accident.

Plan square, portrait and landscape social images by aspect ratio, then crop and resize without sacrificing the subject.

Reduce image bytes with measured resizing and format choices while checking where compression becomes visible.
