Image resizer — frequently asked questions
Is this image resizer free?
Yes. It is completely free with no sign-up, no watermark and no limit on how many images you resize.
How do I reduce an image to 50 KB or 100 KB?
Choose JPG or WebP, type the size you need (for example 50) in “Target size (KB)” and click Resize. The tool lowers the quality, and if needed the dimensions, until the file fits.
Are my photos uploaded to a server?
No. All resizing happens in your browser on your own device. Your images are never uploaded, stored or seen by anyone.
Can I resize many images at once?
Yes. Drop or select multiple images, choose the settings once, click Resize, then use “Download all”.
Will resizing reduce the image quality?
Making an image smaller keeps it sharp — the tool downsizes in steps for better quality. Making an image much larger than the original can look blurry, because new detail cannot be created.
What size is a passport photo in pixels?
A 35×45 mm passport photo at 300 DPI is 413×531 pixels. Pick the “Passport photo” preset to resize to this size.
Which format should I choose — JPG, PNG or WebP?
JPG is best for photos and the smallest file size on most forms. PNG keeps transparency and sharp edges for logos and screenshots. WebP gives small files for websites.
Does it work on mobile?
Yes. It works in any modern browser on Android, iPhone, Windows and Mac.
