Image tools
- Convert AVIF to JPGConvert AVIF images to JPG in your browser so they open in older software. Your browser already decodes AVIF, so no codec is downloaded at all.
- Convert AVIF to PNGConvert AVIF images to lossless PNG in your browser with transparency preserved. Ideal when the file is heading into an editor rather than onto a page.
- Compress a JPGShrink JPG photos in your browser with MozJPEG, the same encoder Mozilla built for the web. Typically 20 to 40 percent smaller than a plain re-save.
- Compress a PNG losslesslyShrink PNG files without changing a single pixel, using oxipng in your browser. No colour quantisation, no upload, and the file is never re-encoded.
- Crop an imageDrag a box over your photo to crop it, right in your browser. Works with the keyboard too, and the picture is never uploaded anywhere.
- Convert JPG to PNGConvert JPG photos to lossless PNG in your browser. No upload and no watermark. Useful when a tool refuses JPEG or you need to edit without further loss.
- Convert JPG to WebPConvert JPG photos to WebP in your browser and cut page weight without a visible quality drop. Nothing is uploaded and no watermark is added.
- Convert PNG to JPGConvert PNG images to JPG in your browser. Pick the quality and the colour that replaces transparency. Files are never uploaded and nothing is stored.
- Convert PNG to WebPConvert PNG images to WebP in your browser with transparency intact. Logos and screenshots get much smaller without the white box JPEG leaves behind.
- Resize an imageChange an image's dimensions in your browser. Set a width, a height or both, keep the aspect ratio, and pick the output format. Nothing is uploaded.
- Rotate or flip an imageTurn a photo by 90, 180 or 270 degrees, or mirror it, right in your browser. Handles the EXIF orientation tag correctly, so nothing rotates twice.
- Convert WebP to JPGTurn WebP images into JPG files that open anywhere, in your browser. Useful when an app, printer or older program refuses to accept a WebP file.
- Convert WebP to PNGConvert WebP images to PNG in your browser, keeping transparency. Expect the file to grow — PNG stores every pixel exactly, artefacts included.
PDF tools
- Turn images into a PDFCombine JPG photos into a single PDF in your browser. Baseline JPEGs are embedded byte for byte, so no quality is lost and nothing is uploaded.
- Merge PDF filesCombine several PDFs into one file in your browser. Text stays selectable, nothing is uploaded, and there is no page limit or watermark.
- Delete pages from a PDFRemove unwanted pages from a PDF in your browser. Blank scans, cover sheets and duplicates go without re-uploading or watermarking the file.
- Rotate PDF pagesTurn sideways or upside-down PDF pages the right way up in your browser. Rotation is lossless and nothing is uploaded or watermarked.
- Split a PDFExtract pages from a PDF in your browser, either as one file or as a separate file per page. No upload, no watermark, no page limit.
Why this works differently
Most free file tools take your document, send it to a server, process it there and send it back. That means waiting for two transfers, trusting a stranger with the contents, and living with whatever file-size cap keeps their bill down.
Modern browsers can do the work themselves. Every tool here decodes and re-encodes your file locally, which removes the upload entirely: the limit becomes your own device's memory rather than someone's quota, and a dropped connection mid-job no longer matters.
