Image Resizer — Resize to Exact Pixels Without Uploading
Updated · Free · No sign-up · Runs in your browser
Resize photos to exact pixel dimensions (1080×1080, 1920×1080, 300×300…), by percentage or by the longest side. Resize up to 20 images at once.
Your images never leave your device: they are processed in the browser with a high-quality resampling filter and are not uploaded to any server.
Or drag and drop · JPG, PNG, WebP · up to 20 images · nothing is uploaded
Need a file under a set size (e.g. 200 KB) instead of exact pixels? Try the image compressor (Korean interface, also runs in your browser).

Worked examples
4000×3000 photo → 1080×1080, fit without cropping
- Scaled to 1080×810, centered
→ 135 px white border top and bottom
4000×3000 photo → 1080×1080, crop center
- Center 3000×3000 area kept
→ 500 px trimmed from each side
3000×4000 photo, longest side 1600
- 1600 ÷ 4000 = 0.4
→ 1200 × 1600 px
How to resize an image to exact dimensions
- Choose your images (or drag them onto the box).
- Pick "Exact pixels" and type the width and height, or tap a preset.
- Choose how to handle a different shape, the file format, then press Resize and download.
Resize without cropping vs. crop to fill
- Fit, no cropping: the whole picture stays visible and borders fill the leftover space.
- Fill and crop center: the picture fills the frame and the edges that do not fit are trimmed.
- Stretch: the picture is squeezed to the exact size (can distort faces).
- Keep aspect ratio: set only the width and each image keeps its own proportions.
Batch resize images locally — nothing is uploaded
All work happens in your browser's memory, so private photos, IDs and documents are never sent anywhere. That also means it works on slow connections once the page has loaded.
Need a smaller file size in KB rather than pixels? Compress the resized image afterwards with a JPG or WebP quality setting — WebP is usually 25–35% smaller than JPG at similar quality.
Frequently asked questions
Are my images uploaded?
No. Images are resized inside your browser and never leave your device. Nothing is stored after you close the page.
How do I resize without cropping?
Set both width and height and choose "Fit, no cropping". The whole picture is kept and white, black or transparent borders fill the gap.
Can I resize many images at once?
Yes. Add up to 20 images, choose the size once and press Resize. Download each file or use "Download all".
Which formats are supported?
JPG, PNG, WebP, GIF (first frame), BMP and AVIF where your browser supports it. Save as JPG, PNG or WebP. iPhone HEIC photos need to be exported as JPG first.
Will resizing reduce quality?
Making an image smaller uses a high-quality filter and looks sharp. Enlarging beyond the original size cannot add detail and may look soft.
How do I keep the aspect ratio?
Tick "Keep aspect ratio" and enter only the width — each image's height is calculated from its own proportions.
