Don't take our word for it — turn off your Wi-Fi. Docexp keeps working. A site that runs with the network off cannot be uploading your files anywhere.
Make your file fit what the form is asking for
Exact pixel size, an exact KB range — including the minimum, which is what actually gets uploads rejected and which almost every other tool ignores. Plus 115 free tools to merge, compress, and convert PDFs, photos, and documents. All in your browser; nothing is ever uploaded.
Fix a photo for an upload form →Batch convert images
Convert and resize a batch of images to JPEG, PNG, or WebP.
Convert and resize a whole folder of images in one go — to JPEG, PNG, or WebP, with an optional maximum dimension. Good for prepping a batch of photos for the web or shrinking a set to email.
How Batch convert images works
- Drop your files into the tool, or click to browse.
- Everything runs in your browser — no upload, no server, no waiting.
- Download your result straight to your device.
Good to know: Everything converts in your browser and downloads as a zip. WebP gives the smallest files for the web, PNG keeps transparency, and JPEG is the safe universal choice for photographs.
