Why Compress Images
Large image files slow down websites, fill up storage, and make sharing harder. This tool lets you reduce file sizes quickly without needing to install anything. You pick the quality level and the tool handles the rest.
Most photos taken with phones or cameras are saved at very high quality settings. You can bring the quality down to 75 or 80 percent and the image looks exactly the same to the human eye, but the file becomes 50 to 70 percent smaller. That means faster page loads, more photos per email, and less storage used.
What This Tool Does
Compress
Reduce file size with a quality slider from 1 to 100. Choose preset levels like High (85%), Medium (60%), or Low (35%) for quick results.
Resize
Change image dimensions by pixel values, percentage, or longest edge. Use presets for social media sizes like Instagram Post, YouTube Thumbnail, or Facebook Cover.
Convert Format
Switch between PNG, JPG, WebP, AVIF, TIFF, and BMP. Pick the format that works best for your use case.
Filters and Adjustments
Apply grayscale, sepia, blur, sharpen, or invert. Adjust brightness, contrast, saturation, and sharpness with simple sliders.
Rotate and Flip
Rotate by 90, 180, or 270 degrees. Flip horizontally or vertically. Fix orientation problems from phone cameras.
Batch Processing
Upload many images at once. They all get processed with the same settings. Download them individually or together as a ZIP file.

Quality Settings Explained
The quality slider controls how much detail is kept in the compressed file. Here is what each range means in practice:
| Quality | File Size Reduction | Best For |
|---|---|---|
| 90 to 100 | 10 to 25% smaller | Photography portfolios, print files |
| 75 to 89 | 40 to 65% smaller | Blog images, product photos, social media |
| 50 to 74 | 60 to 80% smaller | Email attachments, thumbnails |
| Below 50 | 80 to 95% smaller | Preview images, placeholders |
Common Use Cases
Website Speed
Images are usually the largest files on a webpage. Compressing them to quality 75 to 80 makes pages load noticeably faster without visitors seeing any quality drop.
Email Attachments
Most email providers have a 25MB attachment limit. Compressing photos before attaching lets you send more images in a single message.
Social Media
Platforms re-compress your uploads anyway. Uploading already-optimized images gives you more control over how the final result looks.
Storage Space
Phone photo libraries grow quickly. Compressing older photos you rarely look at full-size can free up significant space on your device or cloud storage.
Frequently Asked Questions
What image formats can I compress?
You can upload PNG, JPG, JPEG, WebP, HEIC, HEIF, AVIF, TIFF, BMP, SVG, and GIF files. Output formats include PNG, JPG, WebP, AVIF, TIFF, and BMP.
How much smaller will my images be?
It depends on the image and quality setting. Photos at quality 80 typically become 50 to 65 percent smaller. At quality 60, expect 65 to 80 percent reduction. The actual result depends on image content and original quality.
Can I compress many images at once?
Yes. Upload multiple files and they all get compressed with the same settings. Download them one by one or as a single ZIP file.
Does compression reduce image resolution?
No. Compression only changes file size. The image width and height stay the same. If you also want to change dimensions, use the resize settings.
Do I need to create an account?
No. The tool is completely free with no account, no signup, and no watermarks on your output files.
