Image Resizer
Upload photos, pick a size and see the resized result right away. Common sizes for YouTube, Instagram and blogs are ready as presets, or you can type your own width and height.

How to use
- Drag and drop photos or click to choose them (multiple photos are fine).
- Pick a preset such as YouTube thumbnail or Instagram post, or enter the width and height yourself.
- Choose a fit mode: Fill (crops the overflow), Fit (pads with a background color) or Stretch (ignores the aspect ratio).
- Choose the file format (JPG, PNG, WebP) and quality, and the result size (KB) shows up right below.
- Download a single photo directly, or get several at once as a ZIP.
Platforms change their recommended sizes without notice, so double-check the latest values in the platform's help pages before an important upload.
Tips
Photos come in all kinds of aspect ratios, so fitting them into one fixed size (say 1080×1080) means something gets cropped or padded. If the person or the key subject is in the middle of the photo, Fill is safe in most cases. If the whole photo must show (a group shot, a full product view), choose Fit and set a background color that matches the photo. Stretch can squash or widen the photo when the ratios differ a lot, so we only recommend it for special cases like icons or background textures.
Worried about file size? Choose JPG or WebP and lower the quality slider. Dropping quality from 90% to about 75% often cuts the file size noticeably with hardly any visible difference. When a site has an upload limit, such as blog cover images or social posts, watch the KB number shown with each result as you adjust. Logos or icons that need a transparent background should be saved as PNG to keep the transparency.
When you need many images at the same size (for example 10 product photos for a product page, or a set of screenshots for a blog post), upload them together, apply one setting and download a ZIP instead of saving each file one by one.
FAQ
What happens when a photo has a different aspect ratio than the target size?
It depends on the fit mode. Fill crops the parts that overflow, Fit shrinks the photo so all of it shows and fills the empty space with the background color, and Stretch ignores the original ratio and forces the width and height, so the photo can look squashed.
Which file format should I choose?
For photos with lots of colors, JPG or WebP give smaller files. PNG is better when you need a transparent background or for images with sharp lines like text and shapes. WebP is smaller than JPG at similar quality, but some older programs may not open it.
Can I resize several images at once?
Yes. Upload several photos and they are all resized with the same size and settings. One photo downloads directly; several come as one ZIP file.
Are my photos uploaded to a server?
No. All processing happens inside this browser. Your photos are not sent anywhere.
