Frequently asked questions
How do I reduce a photo to 100 KB (or 50 KB, 20 KB)?
Choose “Target file size”, enter the size in KB or tap a preset, and click Compress. The tool finds the highest quality that fits, and shrinks the dimensions only if it has to.
Will compressing make my photo look worse?
At quality 75–85 most photos look the same to the eye while the file gets much smaller. Very small targets (like 20 KB for a large photo) need lower quality or smaller dimensions, so check the preview.
What is the difference between compressing and resizing?
Resizing changes the width and height in pixels. Compressing keeps the dimensions but stores the image more efficiently. Doing both gives the smallest files.
Which format makes the smallest file?
WebP is usually 25–35% smaller than JPEG at the same quality. JPEG works everywhere. PNG is best for screenshots, logos and images that need transparency, but is large for photos.
Does it remove location and camera data?
Yes. The output never includes EXIF metadata such as GPS location or camera details. Photos are rotated upright first so they still display correctly.
Is there a size limit, and are my images stored?
Images over 4 MB are first shrunk in your browser before upload. Images are processed and immediately discarded; nothing is stored.
