Image Compressor: A Practical Guide
Image compression can make photos easier to upload, share, and publish. The right balance depends on how the image will be used: a small thumbnail needs less detail than a large product image or printed photograph.
When to use Image Compressor
- Reduce photos before attaching them to email.
- Prepare images for website pages and online forms.
- Shrink images that exceed upload size limits.
How to use the Image Compressor tool
- Open Image Compressor and choose a supported image file.
- Select the available compression or quality setting if offered.
- Process the image and download the compressed version.
- Compare the new file with the original at normal viewing size and check that text or fine detail remains clear.
Tips for a better result
- Keep the original for future high-quality exports.
- Resize dimensions as well as compressing when the image will only appear small.
- Use a suitable format: JPEG is common for photos, while PNG can be better for sharp graphics.

Limitations and privacy
Results depend on the input file, browser memory, and the supported features of the PDF or image format. Encrypted, damaged, unusually large, or complex files may fail. PDF Engine is designed for supported processing in your browser, but the page may load third-party JavaScript libraries. Keep the original file and check the output before sharing. For sensitive documents, follow your organization's data-handling rules.
Frequently asked question
Smaller file size can mean some image detail is lost, especially with lossy compression. Test the result before replacing the original.
