Image Resizer
Resize images to any dimension. Free, no signup, no upload.
How It Works
Select an image to see it displayed with its dimensions. Set the desired width and height — keep Lock aspect ratio checked to preserve the proportions — then click Resize. The resized image appears below and downloads as a PNG. No file is ever uploaded to a server.
Why Resize Images?
Resizing helps you optimize images for the web, meet upload size requirements, prepare thumbnails and avatars, fit images into a specific layout, and shrink files for email. Because it runs locally, even large photos resize instantly and stay private.
Resize Images Without Uploading Them
Resizing runs on a canvas inside this page, so the image never travels to a server. Screenshots, ID photos and product shots you have not published yet all stay on your device.
There is no account and no cap on image dimensions or count — the practical limit is your browser's memory, not a free-tier quota.
Frequently Asked Questions
How do I resize an image online?
Select an image, enter the width and height you want in pixels, then click Resize. The resized image appears below, ready to download. There is no signup and no upload.
Are my images uploaded to a server?
No. The image is read and resized entirely in your browser, so it never leaves your device. That makes it safe for private photos and sensitive screenshots.
Can I resize without distorting the image?
Yes. Leave the Lock aspect ratio box checked and the height updates automatically when you change the width (and vice versa), so the image keeps its proportions and does not stretch.
What image formats can I resize?
Any image your browser can open works, including JPG, PNG, WebP, and GIF. The resized image is downloaded as a PNG.
Will resizing reduce the file size?
Making the pixel dimensions smaller usually reduces the file size, which is useful for web pages, email attachments, and upload limits. To compress without changing dimensions, use the Image Compressor.
Is there a limit on image size or how many images I can resize?
No imposed limit. Because resizing happens locally there is no upload quota. Very large images are constrained only by available browser memory.
Do I have to sign up to resize an image?
No. There is no signup and no watermark added to the resized image.
