Resize & crop
Image enlarger
Make images bigger with high-quality resampling. Free, with no upload — your images stay on your device.
Real example
What it does
Twice the width and height means four times the pixels, so the file grows.
Made with this tool on a sample image. Previews are scaled to fit the page; the numbers are from the real files.

Welcome to 2resize. In the next minute, I'll show you how to resize an image, right here in your browser. Your photo appears in the middle. This one is 4000 × 3000 pixels, and almost 3 MB. On the left is your recipe. It already has a Resize step, so just type the width you want. Let's use 800. The height follows automatically, so the picture keeps its shape. Drag the handle to compare. The original is on the left, and the result is on the right. Need a size for social media? Pick a preset, like an Instagram post, or a YouTube thumbnail. You can also scale by percent. 25% makes a quick, small copy. On the right, you can see the new file size before you download anything. When it looks right, click Download. Your photo never leaves your device.
Reference
Every option, explained
Resize step
- Pixels
- Type a width, a height, or both. Leave one empty and it is worked out for you so the image keeps its shape.
- Link button
- Keeps width and height in proportion. Turn it off to set both freely.
- When the shape changes
- Shown when you set both sides. Fill (crop) trims the overflow, Fit inside keeps the whole image, Stretch forces the exact size.
- Size presets
- One-click sizes for Instagram, Stories, YouTube, LinkedIn, X, Facebook, Etsy and more.
- Percent
- Scale from 5% to 400%, with quick buttons for 25, 50, 75, 150 and 200%.
- Longest
- Sets the longest side in pixels. Ideal for a batch that mixes portrait and landscape photos.
- Enter a size in inches, cm or mm plus a DPI, and the pixels are calculated for you.
- Never enlarge small images
- Skips the resize for images that are already smaller than the size you asked for.
Export panel

- Location & camera data
- Always removed from exported files.
- Download
- One image downloads directly. Several download together as a ZIP.

Questions
Is the image enlarger free?
Yes — completely free with no file-size limit, because your own device does the work.
Are my images uploaded?
No. Your images are processed in your browser and never leave your device unless you save them to Studio.
Can I do many images at once?
Yes. Drop a folder or select many files — settings apply to the whole batch, and you can download everything as a ZIP.
