| Your input | Desired result | Starting point | Processing |
|---|---|---|---|
| Existing PDF files | One ordered PDF | PDF Merge | Your browser; page order follows whole-file order. |
| PNG, JPEG, or WebP images | A PDF or a transparent cutout | Image to PDF or Background Remover | Your browser; background removal first downloads a model. |
| A draft or two text versions | Counts, capitalization, or a line comparison | Text tools | Your browser; compare final text with its destination rules. |
| CSV, JSON, encoded text, or a test token | Readable structured data | Developer tools | Your browser; decoding does not establish authenticity. |
| A link or design task | A QR code, palette, credential, or identifier | Generators | Your browser; review the resulting destination or value. |
| A permitted short-term mail test | A receiving inbox | Temporary Email | External provider through our backend; availability and access limits apply. |
Check the receiving format
Before choosing a converter, decide what the recipient or application accepts. Image-based PDF pages do not become editable text. CSV values remain strings, even when they look numeric. Encoded values must use the variant expected by the receiving system. Each tool page includes a sample and explains the limits of its output.
The controls above narrow the list by category or task. With JavaScript disabled, all tool cards remain available. Public tools currently have no usage fee; temporary email has service and abuse-prevention limits.
