How to use Image Resizer
Image Resizer — complete guide
Resizing an image correctly depends on what you're resizing it for. A profile photo or form upload usually needs an exact pixel width and height, or a maximum file size in KB — common for government forms and job portals that reject files over a set limit. A social media post, on the other hand, is better served by a fixed aspect ratio crop (like square 1:1 or portrait 4:5) so the platform doesn't crop it awkwardly itself.
Locking the aspect ratio matters whenever you resize by width or height alone — without it, a photo can end up stretched or squashed. Resizing by percentage is the safest way to shrink an image proportionally without thinking about exact numbers.
If you need to remove a background before resizing, try Background Remover first. Once your image is the right size, you can combine several into a single document with JPG to PDF.
Frequently asked questions
Is this image resizer free?
Yes, with no sign-up and no limit on how many images you resize.
Can I resize to an exact file size, like under 100KB?
Yes. Enter a target size in KB and the tool adjusts quality to get as close as possible while staying under that limit.
Will my photo look stretched after resizing?
Not if you lock the aspect ratio — this keeps your image proportional so nothing looks squashed or stretched.
What crop ratios are available?
Common ratios are available, including square, 4:3, 16:9, 3:4, and 9:16, for social posts, prints, and screens.
Is my image uploaded anywhere?
No. The resizing happens locally in your browser — your photo never leaves your device.
Does this work for ID photo or form-upload requirements?
Yes. You can set the exact width, height, and maximum file size most government and job-portal forms require.
Does this work on mobile?
Yes, the tool is fully responsive on phones and tablets.
