How It Works
Get Your Result in 4 Simple Steps
Get a clean, usable result in just a few clicks — fast, easy, and completely free.
1
Upload Your Image
Drag and drop or select a JPG, PNG, WEBP, or GIF file, up to 20MB, straight into your browser on any device. There's no account to create, no software to install, and no long upload wait before editing begins.
2
Choose Your New Dimensions
Type exact pixel width and height, or drag the percentage slider anywhere from 1% to 200% for quick visual scaling. Lock the aspect ratio to keep proportions accurate, or pick a ready-made social media preset like Instagram Post or YouTube Thumbnail for an exact fit.
3
Rotate, Flip, and Set Quality
Fine-tune rotation in small increments, flip the photo horizontally or vertically to fix orientation, then choose Best, High, Medium, or Small file quality. A live preview and output size estimate show exactly how the result will look before you export it.
4
Preview and Download
Check the estimated output size, confirm the result looks right in the live preview, then download the finished image as JPG, PNG, or WEBP with a single click, ready to post, print, or share anywhere online right away.

FAQs
Frequently Asked Questions
Find answers to the most common questions about this tool.
Yes, it's completely free. Upload a JPG, PNG, WEBP, or GIF file up to 20MB and resize, rotate, flip, or convert it online with no sign-up, no watermark, and no hidden cost involved.
Yes. Type exact pixel dimensions into the width and height fields, or toggle the aspect ratio lock so the image scales proportionally without stretching, squashing, or distorting the original photo at all.
Yes, a percentage slider lets you scale an image anywhere from 1% up to 200% of its original size, which is handy for quick visual resizing without calculating exact pixel values yourself first.
Yes. Fine rotation controls plus horizontal and vertical flip options are built in, so you can straighten a crooked photo or mirror an image in the very same step as resizing it.
You can save the resized image as JPG, PNG, or WEBP, and pick a quality level, Best, High, Medium, or Small file, to balance sharpness against the final download file size for your needs. If a form or portal needs an exact size like 20KB or 50KB, see our full guide on <a href="https://toolflexy.com/resize-image-to-20kb-50kb-free/">how to resize an image to 20KB, 50KB, or any exact size</a>.
No. The Image Resizer runs 100% in your browser — your image is never uploaded to a server at any point, so there is nothing to store or delete afterward. All resizing, rotating, flipping, and format conversion happens locally on your own device.
Files up to 20MB are supported, plus ready-made presets for Instagram Post, Instagram Portrait, Story/Reel, Facebook Post, YouTube Thumbnail, X Header, and LinkedIn Cover, so you can match exact platform dimensions in one click without guessing numbers yourself.
Yes. ToolFlexy's Image Resizer accepts files up to 20MB, so you can resize an image to 20MB or well below it without hitting an upload error. Just drag your file in, set your target dimensions or percentage, and download the resized result, no sign-up and no software needed.
Turn on 'Lock aspect ratio' before entering a new width or height — the tool automatically calculates the matching dimension so your image scales proportionally instead of looking stretched or squashed.
The resized result will be a single still frame, not an animated GIF — the editor's canvas-based preview can only capture one frame at a time, so animation is not preserved through a resize. If you need to keep a GIF animated, resize the source video or frames before converting to GIF instead.
