Your images are processed locally in your browser and never uploaded to any server.
Resize settings
Enter the exact width and height in pixels.
The aspect ratio is locked. Changing one side updates the other.
The whole image fits inside your target size and the ratio is preserved. Some space may remain empty.
This browser cannot encode AVIF. AVIF output is disabled.
PNG is always saved losslessly; no quality setting is needed.

What is an image resizer?
An image resizer changes the width and height of an image — to fit a website, a social-media post, a presentation, or a print layout. This tool does it locally in your browser, so your photos never leave your device.
You can set the exact pixel size, scale by a percentage, or start from a social-media preset. You decide how the image should reach the new size (fit, fill, or pad), which format to save it in, and how much quality to keep. Up to 10 images can be processed in one batch, and animated GIFs keep their frames and timing.
Resize images in 3 steps
- 1
Add your images
Upload up to 10 images (25 MB each). They stay on your device.
- 2
Choose a size
Pick exact pixels, a percentage, or a preset — then pick fit, fill, or pad.
- 3
Download your images
Preview the result and download each image, or all of them as one ZIP file.
Input and output formats
Load JPG, PNG, WebP, GIF, AVIF, or TIFF — and save as JPG, PNG, WebP, or AVIF with a quality slider when the format supports it.
Input formats
JPG/JPEG, PNG, WebP, GIF, AVIF and TIFF are accepted. For multi-page TIFF files, the first page is used.
Output formats
Save as JPG, PNG (always lossless), WebP, or AVIF. When the browser supports it, you can also keep the original format.
Animated GIFs, preserved
Animated GIFs are resized frame by frame. Every frame, its delay, and the loop setting are kept, so your animation still plays after resizing.
TIFF files
Browsers cannot export TIFF, so the first page of a TIFF is converted to PNG before resizing. Your output is still a properly sized PNG.
Three ways to set the size
Use the method that fits your task: exact pixels for precision, a percentage for quick scaling, or a preset for social media.
Exact pixels
Type the width and height you want. Lock the aspect ratio so the image is never stretched out of shape.
Percentage
Scale up or down with quick steps from 25% to 200%, or type any custom value.
Social presets
Start from a ready size for Instagram, Facebook, YouTube, TikTok, LinkedIn, Pinterest, and X.
Fit, fill, or pad
The resize mode decides what happens when your target size and the image ratio do not match.
Fit
The whole image fits inside your target size and the ratio is preserved. Some space may remain empty.
Fill
The image is scaled until it covers the whole target size. Parts that do not fit are cropped away.
Pad
The image fits inside the target size, and the remaining space is filled with your background color — or left transparent.
A quality setting for every format
JPG, WebP, and AVIF use a quality slider (10–100%) so you can balance file size and sharpness. PNG is always lossless, so it needs no quality setting at all.
Your images never leave your device
All processing happens in a secure web worker inside your browser. No image is uploaded, stored, or shared — even “download” only writes a file back to your own device.
Limits
- Up to 10 images per batch.
- Each image can be at most 25 MB.
- The result is limited to 16,384 pixels per side and 50 million pixels per image.
- Upscaling is allowed but may reduce sharpness — you will see a warning.
- WebP and AVIF support depends on your browser. If it is missing, the tool falls back to PNG.
Frequently asked questions
Does the image resizer upload my photos?
No. Every step — decoding, resizing, and re-encoding — runs locally in your browser. Your images are never sent to a server, so the tool works even when your internet connection drops.
Which file types can I resize?
You can open JPG/JPEG, PNG, WebP, GIF, AVIF, and TIFF files up to 25 MB. You can save the result as JPG, PNG, WebP, or AVIF (PNG is always lossless).
How do animated GIFs behave after resizing?
Each frame is resized separately and re-assembled with the original delays and loop count, so the animation still plays exactly as before — just at the new size.
What is the difference between fit, fill, and pad?
Fit keeps the whole image inside your size box and preserves the ratio. Fill scales the image until it covers the box, cropping the overflow. Pad keeps the whole image and fills the empty space with your background color or transparency.
Can I resize more than one image at once?
Yes. Add up to 10 images, pick the settings once, and they are all resized with the same rules. Then download them individually or as a single ZIP file.
What happens if I choose a size larger than the original?
Upscaling is allowed, and you will see a note that enlarging cannot add detail. The output is still created at the size you asked for.
Why is TIFF converted to PNG?
Browsers cannot write TIFF files, so the first page of a TIFF is converted to PNG. The size you chose is still applied exactly.
Is there a file size limit?
Each file can be at most 25 MB, and up to 10 files can be processed in one batch. The generated image is limited to 16,384 pixels per side and 50 million pixels per image, which covers any real-world use case.
Does it work on my phone?
Yes. The resizer is a regular web page with no app to install — it works in any modern browser on phones, tablets, and desktops.
How do I download the resized images?
Open the results section and use “Download” next to each image, or “Download all (ZIP)” to get every result in one ZIP file. Files are saved directly on your device.
