Increase Image Size
Increase image pixel dimensions 2–4× in your browser.
Best for bigger dimensions. Example: take a 500px image up to 1500px.
Before you use: the bigger you go, the softer fine detail can look.Best for: raising dimensions and resolution. Not ideal for: reducing file size.
- Add the image.
- Increase its width, height and resolution.
- Save the larger image.
Increase Image Size is a browser-based image tool on ImgToolsBase. Increase image pixel dimensions 2–4× in your browser. To use it, upload or drop your image and view the result directly in your browser — no signup and nothing to install.
How this tool works
What it does
Increase Image Size enlarges pixel dimensions via canvas resampling.
Scale
Up to 4×, pixel-budget guarded.
Output
PNG/JPG/WebP with quality.
Honesty
No new real detail is created. Browser canvas export strips EXIF, GPS, and most other source metadata.
Increase Image Size in your browser
Increase Image Size enlarges an image to bigger pixel dimensions using browser canvas resampling. It does not add new real detail — it scales the pixels you already have, so very small or blurry images may still look soft when enlarged.
Pick a scale (up to 4×), optionally sharpen the result, and choose your output format. PNG and WebP can preserve transparency when the source has an alpha channel and Background is set to Transparent; JPG output is flattened onto your fill colour.
Increase Image Size shows the original and new dimensions, the scale used, the output format, and the file size. Browser canvas export strips EXIF, GPS, and most other source metadata. Animated GIFs are processed as a single still frame; animation is not preserved.
How to use Increase Image Size
- Upload your image into Increase Image Size — click, press Enter, or drag it in.
- Choose how much to enlarge (the new pixel size is shown after processing).
- Optionally sharpen the enlarged result, then choose PNG, JPG, or WebP output.
- Click Process, then download the larger image.
Why use Increase Image Size
Scale up to 4× the pixel size.
Add a little edge clarity after scaling.
Resampling, not new detail.
PNG/WebP can preserve transparency only when source alpha exists and Transparent background is selected; JPG flattens.
Common uses for Increase Image Size
Reach a minimum pixel size for a template.
Enlarge before adding text or borders.
Meet a site’s minimum dimensions.
Export larger as PNG, JPG, or WebP.
When to choose Increase Image Size
This tool is for making an image physically larger in pixels for a banner or print slot.
Worked example: A header image needs to span a wider layout. Increase its size to the required width so it covers the area without tiling or gaps.
Increase Image Size is Image Upscaler by another name; to shrink or set an exact size, use the image resizer.
- Decide the target dimensions from the space you need to fill.
- Very large jumps in size show softness, so enlarge only as much as needed.
Will increasing the size make the image blurry?
Large increases soften detail because pixels are interpolated; keeping the jump modest limits the effect.
Is increasing size the same as zooming?
It produces a genuinely larger image file rather than just a zoomed view, so the result can be placed at the new size.
Frequently asked questions
Does Increase Image Size add real detail?
No. Increase Image Size resamples existing pixels to larger dimensions. It cannot invent detail, so soft or tiny images may still look soft.
How much can Increase Image Size enlarge?
Up to 4×, within a browser pixel budget. Very large results may hit a memory limit and show an error.
Will Increase Image Size make my image print sharper?
It increases pixel dimensions, which can help layout, but it does not create new detail; print sharpness depends on the original.
Can I export Increase Image Size as JPG or WebP?
Yes — the enlarged image saves as PNG, JPG, WebP, or same-as-input, with a JPG and WebP quality control.
