Useful tools. Simple solutions.

Percentage Calculator

Find X% of a number in seconds.

Formula: percentage ÷ 100 × number.

Image Resizer & Compressor

Resize an image and export a smaller JPG directly in your browser.

Processing happens locally in your browser; images are not uploaded by this tool. Output is JPG, so transparency may be replaced with a background.

Image to PDF

Select one or more images to create a downloadable PDF. Each image becomes a page.

Images are processed locally in your browser. Very large image sets may use significant phone memory.

PDF Merge & Split

Combine multiple PDFs into one file, or extract a page range from one PDF.

PDFs are processed in your browser and are not uploaded by this tool. The PDF library loads from a CDN, so internet access is needed.

QR Code Generator

Create a QR code for a website link, text, phone number or other short content.

The QR library loads from a public CDN, so an internet connection is required to generate the code. Avoid putting passwords or private information in a QR code.

Word Counter

Count words, characters, sentences and paragraphs as you type.

Your text is counted in this browser and is not uploaded by this tool.

Password Generator

Generate a random password using your selected character types.

Password generation uses your browser's cryptographic random generator. Do not share your password; store it in a trusted password manager.

Image Watermark Remover / Cropper

Select an image and crop out the watermark area. This crops pixels; it does not reconstruct hidden content or remove every watermark automatically.

Video Compressor

Re-encodes a video to WebM in supported browsers. Output may not be smaller, and audio support varies by device.

PDF Compressor

Re-saves a PDF using the browser PDF library. This may clean up structure, but cannot reliably reduce scanned-image PDFs.

PDF Signer

Place a visible typed signature on a selected page. This is not a certificate-based digital signature.
