Why Resize an Image?
Pictures from a phone or camera are often far bigger than you need. Resizing changes the width and height in pixels, which also makes the file smaller. These are the most common reasons people resize images:
- Forms and portals. Job applications, exam forms, and government sites often ask for a photo or signature of an exact size.
- Websites and blogs. Smaller pictures load faster, which helps visitors and search rankings.
- Email and chat. A resized picture is quick to send and does not fill the mailbox.
- Social media. Profile pictures, covers, and posts each work best at a certain size.
- Phone storage. Smaller copies of big photos save space.
Common Image Sizes
- 1280 x 720. HD size, used for YouTube thumbnails and video covers.
- 1920 x 1080. Full HD, used for wallpapers and website banners.
- 1080 x 1080. Square size for Instagram posts.
- 800 x 800. A good square size for online shop products.
- 400 x 400. A common size for profile pictures.
Tips for Better Results
- Keep Keep aspect ratio on, unless you need an exact width and height of a different shape.
- Make pictures smaller, not much bigger. Enlarging a small picture makes it look soft.
- Want the file even smaller? Compress it with the Image Compressor after resizing.
- Need a different format? Use the WebP to PNG and JPG converter, or the HEIC to JPG converter for iPhone photos.
- Want to put the pictures in one document? Use the JPG to PDF converter.
- Making a YouTube video? Save a thumbnail with the YouTube Thumbnail Downloader.
Is It Safe to Resize Images Online?
Many online tools upload your pictures to a server. BixTools works differently. Your image is opened and resized inside your own browser, so it never leaves your device. We do not store, share, or look at your files.

Frequently Asked Questions
Is this image resizer free?
Yes. BixTools is completely free. There is no signup, no watermark, and no limit on how many images you resize.
Is my image uploaded to a server?
No. Your image is opened and resized inside your own browser, so it never leaves your device. We do not upload or store your pictures.
How do I resize an image?
Add your image, type the width or height you want, or tap a quick button such as 50%. Then click Resize and click Download.
What does keep aspect ratio mean?
It keeps the width and height in proportion, so your image does not look stretched or squashed. When you change one side, the other side updates automatically.
How do I resize an image to an exact size in pixels?
Type the width and the height you need in the two boxes. If you want an exact width and height that do not match the original shape, turn off Keep aspect ratio first.
Will resizing reduce the image quality?
Making an image smaller keeps it sharp. Making it much larger than the original can make it look soft, because the extra detail does not exist.
Which image formats are supported?
You can resize JPG, PNG, and WebP images. The result is saved in the same format as your original image.
How do I make an image file smaller?
Reducing the width and height makes the file smaller. For an even smaller file, run the resized picture through the Image Compressor and lower the quality.
What is the largest size I can set?
You can set the width and height up to 10,000 pixels each. Very large pictures use a lot of memory, so on a phone a smaller size works better.
Does the tool change my original file?
No. Your original file is never changed. The tool makes a new, resized copy that you download.
