How to use Image Enlarger
- Upload the image you want to make bigger.
- Enter a percentage above 100, or switch to exact width and height.
- Choose an output format — PNG if you will edit further.
- Compare the result before downloading.
About this tool
The Image Enlarger scales images up by percentage or to exact dimensions using your browser’s high-quality resampling. It will not pretend to "enhance" anything: enlarging interpolates between existing pixels, so a bigger image is always a softer one. The tool opens with enlarging enabled and tells you honestly what to expect.
Recommended settings
Settings we suggest
- Stay at or below 2× for results that still look natural.
- Enlarge from the sharpest, least-compressed original you have.
- PNG output avoids stacking JPEG artefacts on top of the softness.
Supported formats
Input: JPEG, PNG, WEBP, AVIF, GIF, BMP. Output: PNG, JPEG, WEBP.

Quality & file size
Lossy formats (JPEG, WebP, AVIF) trade detail for smaller files as you lower the quality; PNG stays lossless regardless of the slider. The tool always shows the original and result sizes so you can judge the trade-off, and it never recommends a result that is larger than your original as an “optimisation”.
Privacy
Every image is decoded, transformed and re-encoded entirely in your browser using the Canvas API and a Web Worker. Files are never uploaded, are not stored in localStorage, and are cleared from memory when you remove them or close the page.

Common issues & limitations
- Upscaling cannot create detail that is not in the source; there is no AI reconstruction here.
- Noise, grain and JPEG artefacts are magnified along with the image.
- All processing happens on your device; nothing is uploaded, so very large batches are limited by your available memory.
Frequently asked questions
Does enlarging add detail to my image?
No, and no honest tool can claim otherwise without AI. Enlarging interpolates between the pixels you already have, so the result is bigger but softer. We say so plainly rather than promising "enhancement".
How far can I enlarge before it looks bad?
Up to about 2× is usually acceptable for photos, especially if the image will be viewed at a distance or on screen. Beyond 3× the softness becomes obvious on almost any source.
What enlarges well?
Sharp, well-lit, low-noise photos and screenshots taken at native resolution. Already-compressed JPGs enlarge badly because upscaling magnifies their artefacts along with the picture.
Should I use PNG for the output?
Yes if you plan to edit further — PNG is lossless, so the enlarged pixels survive intact. Use JPG or WebP if the enlarged image is the final deliverable.
Are my images uploaded to a server?
No. Every image is decoded, processed and encoded entirely inside your browser using the Canvas API. The files never leave your device and are discarded when you close the page.
