Free Online Image Tools — Compress, Resize, Convert & Edit

How to choose the right free online image tool

Start by identifying the result you need. Use an image compressor to reduce file size, a resizer to set exact dimensions, a converter to change file formats, or an editor for cropping, rotating, flipping, adding text, and watermarking. Open the tool that matches your task, upload your file, review the available settings, and check the preview before exporting. Choosing the right tool at the beginning helps preserve image quality and avoids unnecessary repeated edits.

ImgSwift brings common image and PDF tasks together in one place. Depending on the selected tool, you may be able to adjust output dimensions, quality, format, crop area, background, or other settings. Available controls and supported formats can vary by tool, so review its options before processing your file.

Common image tasks

• Smaller files: use an image compressor and compare output size and visual quality before publishing.
• Correct dimensions: use an image resizer or crop tool; keep the aspect ratio when you do not want the image stretched.
• Web compatibility: convert to a format supported by your destination, such as JPG, PNG, or WebP when offered by the selected tool.
• Social profiles and posts: choose a social-media resizer or thumbnail tool that matches the platform's requested dimensions.
• PDF tasks: open the PDF Tools category and check each tool's supported input and output before uploading.

Get better results

• Keep a backup: save your original image or PDF before making changes, especially when replacing dimensions or format.
• Review quality: after compression or conversion, compare the result with the original to check sharpness, colors, and file size.
• Use exact dimensions: when a website or social platform specifies pixel dimensions, enter those values where the tool provides width and height controls.
• Choose transparency carefully: if an image needs a transparent background, use a supported format such as PNG and verify the downloaded file.
• Check the export: open the downloaded file and confirm it looks right before publishing, sharing, or deleting the original.

Privacy and processing

Processing methods can differ between tools. Some browser-based tools process files on your device, while others may send files to a server to complete the task. Check the selected tool page and ImgSwift Privacy Policy for details about file handling and any temporary-file retention. Avoid uploading sensitive files unless you are comfortable with the tool's stated processing method, and keep your original file until you have verified the download.
