About Local File Tools
Local File Tools is a collection of free, browser-based image and PDF tools for people who do not want to upload a file just to change it. You can resize images, convert common photo formats, merge or split PDFs, turn PDF pages into images, build a PDF from photos, and remove hidden photo metadata without creating an account.
How it's built
This is a static site with no backend and no file-upload path. Image work uses browser APIs, PDF work uses JavaScript libraries loaded only when needed, and expensive operations are isolated from the interface. Your browser reads the selected file and creates the result on the same device; the file bytes are not sent to Local File Tools or a conversion API.
Clear limits
Browser-only processing trades remote server capacity for privacy and immediacy. Each tool explains its supported formats, file and batch limits, browser requirements, and known format caveats before you start. Unsupported or damaged files produce an error in the tab rather than being uploaded somewhere else for a fallback conversion.
Open source
The full source is public, so you don't have to take the privacy claims on faith. You can read exactly what each tool does, or run it yourself. Bug reports and pull requests are welcome.
