Start at 75 to 85% quality for most images
This range typically looks identical to the original on screen while cutting file size significantly. Only drop lower if you need to hit a strict size limit, like a form or portal cap.

Help & Tips
Get the best results from Image Compressor
Use target file size when you have a strict upload limit
If a form, application, or portal caps uploads at a set size, like 100KB or 200KB, enter that target directly instead of guessing a quality percentage. The tool adjusts compression automatically to fit.
Convert to WebP first if the platform supports it
WebP compresses noticeably smaller than JPEG or PNG at the same visual quality. If your website or app accepts WebP, compressing in that format gives you the smallest possible file.
Keep PNG for images that need transparency
Compressing a PNG keeps its transparent background intact. Don't switch to JPEG just to save space if your logo, icon, or graphic relies on a see-through background.
Compress before uploading to social platforms
Instagram, LinkedIn, and other platforms apply their own compression on top of yours. Starting with a well-compressed, high-quality file gives you more control over how the final image looks.
Batch compress when optimizing a whole website or folder
If you're preparing many images for a website launch or migration, upload them together and apply the same quality setting instead of compressing each file one by one.

Frequently Asked Questions
Is this image compressor free to use?+
Yes, completely free. You can compress images without creating an account or purchasing a subscription. There are no hidden limits on the number of images you can compress.
Will compressing reduce my image quality?+
It depends on the setting. Lossless compression removes hidden metadata and redundant data without any visible change. Lossy compression, controlled by the quality slider, reduces file size further and a setting of 75 to 85% typically looks identical to the original on screen while cutting file size significantly.
How much smaller will my image get?+
Savings depend on the source format, existing compression, dimensions, and selected settings. Review the actual result and its displayed size.
Can I compress an image to a specific file size, like under 100KB?+
Yes. Enter a target file size and the tool adjusts quality automatically to get as close as possible while keeping the image usable. This is useful for forms, portals, or applications with strict upload limits.
Can I compress multiple images at once?+
Yes. Add up to 50 images and apply shared quality and format settings. Each image is processed separately, and Download All creates a ZIP in your browser.
What image formats are supported?+
You can upload and compress JPG, PNG, WebP, and GIF files. The tool automatically applies the most effective compression method for each format.
Are my files stored on your servers?+
Each image is temporarily uploaded for processing and cleaned up after the request completes. No account is required.
