Resize an image
Exact pixel dimensions, with or without the aspect ratio.
Leave height blank to keep the aspect ratio. Images are never enlarged past their original size.

How it works
- Add your images — Drag, click or paste. Several at once all get the same dimensions.
- Give a width, a height, or both — Leave one blank and the aspect ratio is kept automatically.
- Choose how it fits — "Fit inside" keeps the whole image within your box. "Fill and crop" fills the box exactly, trimming the overflow.

Fit inside versus fill and crop
"Fit inside" treats your numbers as a maximum. A 4000×3000 photo asked to fit 1920×1920 comes out 1920×1440 — the whole picture, nothing lost, but not exactly the dimensions you typed.
"Fill and crop" treats them as exact. The same photo asked for 1920×1920 comes out precisely 1920×1920, with the sides trimmed. Use it for avatars, thumbnails and anywhere a layout demands a specific shape.
Why it will not enlarge your image
Asking for 4000 pixels from a 1200-pixel source cannot add detail that was never captured — it produces a blurry 4000-pixel file that is slower to load and no better to look at. Tools that offer it are selling an illusion, so this one stops at the original size.
If the image is genuinely too small for what you need, the answer is a bigger original, not a bigger file.
Resizing versus compressing
People often search for "resize to 50 KB", which is really a compression question — kilobytes are a file-size target, not a dimension. If a limit in KB is what you are up against, the compress tool is the one that solves it, and it will resize as part of getting there.
Use this page when you know the pixels you want: a 1920px banner, a 512px icon, a photo scaled for a slide.
Common questions
- How do I keep the aspect ratio?
- Fill in only one of width or height and leave the other blank. The missing side is calculated for you.
- Can it make an image bigger?
- No. Enlarging cannot recover detail that was never in the file, so resizing stops at the original dimensions.
- Can I resize several images at once?
- Yes — every image you drop in gets the same settings.
- What happens to transparency?
- It survives if you choose PNG or WebP output. JPEG has no alpha channel, so transparent areas are flattened onto white.
- Does it work on HEIC photos from an iPhone?
- Yes. HEIC is decoded first, then resized.
