Which tool do I need?
If a form has rejected your upload, start from the requirements database, pick the portal and the photo maker applies every rule at once. If you just need a file under a certain size, use Compress image or Compress PDF and type the limit. To edit a PDF's text, convert it with PDF to Word; to feed it to an AI tool, use PDF to Markdown.
Why your files are not uploaded
Each tool is a small program that your browser downloads once and runs locally. Your file is read from your disk into the page, processed in memory and saved straight back. That is why there is no queue and no account, and why most tools keep working if you go offline after the page has loaded. Files up to 300 MB are accepted; the AI tools download their model once before their first use.
