File Fixer

File Fixer helps you prepare images that websites refuse to upload. It detects file upload fields and visible website requirements such as accepted formats, maximum file size, and image dimensions. When an image does not meet those requirements, File Fixer can convert, compress, or resize it directly in your browser. Features: • Detects image upload fields and nearby requirements • Checks file size, format, and dimensions • Converts between JPEG, PNG, and WebP • Compresses oversized images • Resizes images when needed • Auto, High Quality, and Small File optimization modes • Paste images directly from your clipboard • Edit image dimensions manually • Optional Auto Fix mode • Download the repaired image with a clear “-fixed” filename Your images are processed locally in your browser. File Fixer does not upload your images to its own servers. Current beta support: JPEG, PNG, and WebP. Some websites do not expose all of their upload restrictions, so File Fixer may not always be able to detect every hidden requirement. Extremely large images may also be rejected when they cannot be processed safely in the browser.
