File Converters
Forms and websites are picky about formats: the photo must be a JPG, the documents must be one PDF, the screenshot must not be a HEIC. These converters change formats in your browser — no uploads, no watermarks, no “premium” download button. The first converters below launch with the site; the format converters and PDF tools follow right after.
Image to PDF
Combine images into a single PDF, with an option to keep the finished PDF under 200KB for form uploads.
JSON to TOON Converter
Convert JSON to the compact TOON format and cut the token cost of feeding structured data to AI models.
LLM Token Cost Calculator
Estimate token counts and API costs for your prompts across popular AI models before you send them.
HEIC to JPG
Convert iPhone HEIC photos to JPG so any form or website will accept them.
WebP to JPG
Turn WebP images downloaded from the web into standard JPG or PNG files.
AVIF to JPG
Convert newer AVIF images into JPG files that open everywhere.
Compress PDF to KB
Shrink a PDF to the exact KB limit a form sets — 200KB, 300KB, 500KB and more.
Merge & Split PDF
Combine several PDFs into one, or split one PDF into separate files — in your browser.
