Choose a tool by the result you need

Prepare an image for an upload

Use Image Resizer when a form requires specific pixel dimensions. Use Image Compressor when the file must fit a size limit. Changing dimensions and lowering encoding quality are different steps; inspect the downloaded copy before replacing an original.

Assemble a PDF document

Use PDF Splitter to select pages, then PDF Merge to combine documents in order. The PDF Compressor rebuilds pages as images, so read its limitations before using it on searchable text, forms or signed documents.

Check a sale or a written draft

The Profit Margin Calculator deducts the costs you enter and shows the remaining margin. The Word Counter checks plain-text length while you edit. Each page explains its inputs, examples and limits so you can interpret the result.

What local processing means

Where a tool states that processing is local, the file or text is processed in your browser. The website still downloads scripts and may use analytics, consent and advertising services. See our Privacy Policy for details. Keep original files, and report a tool issue with a non-sensitive example if a result looks wrong.
