About Resize Image
Websites, forms and email often want images of a specific size. This tool resizes JPG, PNG, WebP, HEIC and other images, one at a time or a whole batch. Set an exact width and height, just one side to keep the proportions, a percentage, or a maximum length for the longest side. When you set both dimensions, choose to fit inside them, fill them exactly by trimming the edges, or stretch. Save in the same format or switch to JPG, PNG or WebP.

Why resize an image?
Every place you use an image expects a certain size. Social networks crop and scale uploads to their own dimensions, online shops want product photos of the same size, websites load faster with images no bigger than they're displayed, and many forms require exact dimensions such as 600 × 600 pixels for a profile photo. Resizing gets your image to the right size before you upload it, so it isn't cropped or squashed unexpectedly.
Smaller dimensions also mean smaller files: halving the width and height of a photo cuts its pixel count to a quarter, which usually shrinks the file by a similar amount.
Resizing a whole batch at once saves a lot of time when you're preparing product photos, a photo gallery or images for a presentation, since every image ends up with consistent dimensions.
Pixels, percentage or longest side?
Set an exact width and height when a site asks for specific dimensions. Fill in just the width or just the height when you only care about one side; the other is calculated so the image keeps its proportions. Use a percentage, such as 50%, to scale a whole batch evenly. Longest side is ideal for a mixed batch of portrait and landscape photos: set it to 2000 and every image ends up no more than 2000 pixels on its longest edge, whatever its orientation.
Fit, fill or stretch?
When you set both a width and a height, the image's shape may not match. Fit keeps the whole picture inside the box, so one side may come out smaller than you asked. Fill makes the image exactly the size you set by trimming the edges evenly, which is what you want for square profile pictures and thumbnails. Stretch forces the image to the exact size and distorts it, so use it only when distortion doesn't matter.
For full control over what gets trimmed, crop the image first, then resize it.
Popular image sizes
Instagram posts look best at 1080 × 1080 (square) or 1080 × 1350 (portrait). A Facebook or LinkedIn cover is around 1584 × 396 for LinkedIn and 820 × 312 for Facebook pages. YouTube thumbnails are 1280 × 720. For a website hero image, 1920 pixels wide is plenty, and 1200 pixels suits most blog images. For email, 800–1200 pixels wide keeps messages light.
You can save in the original format or switch to JPG, PNG or WebP at the same time. If the resized file still needs to be smaller in KB, follow up with the image compressor.
Questions
Will resizing keep the proportions?
Yes, unless you choose Stretch. Set only the width or only the height and the other side is calculated for you.
Can I make an image bigger?
Yes, but enlarging can't add detail, so big increases look soft. Shrinking always looks sharp.
What is the difference between fit and fill?
Fit keeps the whole image inside the size you set, so one side may be smaller. Fill makes the image exactly that size by trimming the edges evenly.
Is metadata kept?
No. Resized images are saved without camera details or GPS location.
Are my images uploaded?
No. Images are resized in your browser.
