Practical help with compressing, resizing and converting photos, removing plain backgrounds, extracting text with OCR and making passport photos at home.
Most image problems come down to three things: the file is too big, it's the wrong shape, or it's in a format the destination won't accept. Upload forms add their own rules, like a photo under 50 KB or exactly 600 by 600 pixels, and a rejected upload rarely explains why.
The guides in this section explain how compression, resizing and formats actually work, then show the steps with ToolMany's browser-based image tools. You'll also find practical advice on taking passport photos at home, removing plain backgrounds from logos, and getting accurate text out of photos with OCR.
