Image & File Tools
Most online image and PDF converters ask you to upload your files to someone else's server. The tools in this category take a different approach: your files are opened and processed by your own browser, and the results are created on your device.
That makes them a sensible choice for personal photos, scanned documents and anything you would rather not hand to a third party. It also means the practical limits depend on your device's memory, which each tool page explains.

Common jobs and which tool to use
To make photos lighter for a website or email, use the Image Compressor, and combine it with the Image Resizer when the pixel dimensions are larger than they need to be — resizing usually saves more space than compression alone. The Image Format Converter switches between JPEG, PNG and WebP, and the Image Cropper trims to an exact area or aspect ratio.
The Image Color Picker reads exact HEX and RGB values from any pixel, and the QR Code Generator creates downloadable codes for links, text, Wi-Fi details and contact information.
For documents, the PDF Merger and Splitter combines files or extracts page ranges, and the PDF to Image Converter renders pages as PNG or JPEG images.
Supported formats and file sizes
Image tools accept JPEG, PNG, WebP, GIF (first frame only), BMP and, in browsers that support it, AVIF. Output formats are JPEG, PNG and WebP. To keep the page responsive on phones and older computers, individual images are limited to 25 MB and PDFs to 100 MB. Very large images — roughly above 16,000 pixels on a side — can exceed what a browser canvas is able to hold; the tools report this clearly rather than producing a broken file.
