Simple and Accurate Image Resizing Online
Sometimes you just need a quick resize. Sometimes you need precise dimensions for printing, a strict file size limit, or a batch export for a website. This tool covers all of that in one place.
You can resize images by exact width and height or use percentage scaling. Enter 50 percent to cut an image in half. A 1000 × 1000 image becomes 500 × 500, no extra math.
Resize in pixels, centimeters, millimeters or inches
Choose the unit that matches your task. Pixels are perfect for web and UI work. Centimeters, millimeters and inches are useful when you prepare images for print, documents, or templates that rely on real world sizing.
When you pick a unit other than pixels, you can set DPI. That gives you predictable results for print workflows because the tool converts your target size into pixels using the DPI you choose.
Keep aspect ratio, stretch, or fit with background fill
If you enable Keep aspect ratio, the image stays proportional and will not look distorted.
If you disable it, the tool will stretch the image to match your exact width and height. This can be useful for placeholders or specific layouts.
Need a fixed canvas size without stretching the photo? Turn on background fill. The image will fit inside the target size and the remaining area can be filled with a color or left transparent. It is handy for thumbnails, banners, product images and social templates.
Batch resize up to 10 images
Upload up to 10 files and resize them in one go. It saves time when you prepare a folder of photos for a blog post, Shopify products, a portfolio, or social media.
Reduce image size in KB for JPG and WEBP
When file size matters, use the max size option. It helps you create lighter images for websites, forms, email attachments, or platforms with upload limits. For example, you can target results like 100 KB, 50 KB, or 20 KB when exporting to JPG or WEBP.
Export as JPG, PNG, WEBP or keep original
Choose the output format that fits your goal:
- Original format when you only need resizing
- JPG for smaller file sizes
- WEBP for modern web performance
- PNG when you need transparency or lossless quality
Quick edits before resizing
Before you export, you can rotate the image or flip it horizontally or vertically. These small fixes are often all you need, without opening a separate editor.
Common use cases

- Create consistent product images for Shopify
- Prepare images for Instagram without manual guessing
- Resize for documents using cm, mm or inches with DPI
