Image Resizer: Resize Photos by Pixels or Percent, Batch Free

About the Image Resizer

Resizing an image sounds simple until you need an exact pixel size, a clean aspect ratio, or fifty photos done at once. This resizer handles all three. Drop one image or a whole folder, choose how you want them sized, and download the results — with everything happening in your browser, so your photos are never uploaded.

It's built for the real reasons people resize: hitting an upload limit, fitting a social-media template, shrinking a batch for the web, or making a thumbnail. Aspect ratio is preserved by default, so nothing comes out stretched unless you ask for it.

Three ways to resize

Percentage — scale everything to, say, 50% or 200% of its original size. Always proportional.
Fit to width/height — set a maximum width and/or height; each image shrinks to fit inside, keeping its shape. Perfect for "make these no wider than 1280px."
Exact size — type a precise width × height or pick a social preset (Instagram, Facebook, X, YouTube, LinkedIn, Pinterest, TikTok, and more). Choose how to handle a different shape: crop to fill, pad to fit, or stretch.

More control

Batch everything. Resize a whole set at once and download them as a single ZIP, or grab them one at a time.
Convert while you resize to JPG, PNG, or WebP — or keep the original format — with a quality slider for the lossy ones.
Padding your way. When you pad to an exact size, choose a background color or keep it transparent (PNG/WebP).
Never accidentally upscale. Leave "Don't enlarge" on and small images stay sharp instead of being blown up.

Tips

For web pages and email, "Fit to width/height" with a max width around 1200–1600px is the sweet spot.
For social, use a preset and "Crop (cover)" so the image fills the frame edge to edge.
Switch to WebP to get noticeably smaller files at the same visual quality.
Need to squeeze the file size down further after resizing? Send it through the Image Compressor.

No account, no watermark, and no upload — just drop, size, and download.

Common questions

How do I resize an image to specific dimensions?

Enter the exact width and height in pixels (or scale by percentage) and download. Keep the aspect ratio locked to avoid distortion, or crop to fit when the target shape differs from the original.

How do I resize a photo for Instagram or other social platforms?

Pick the platform preset and the resizer targets the right dimensions, so posts and covers arrive sharp instead of being mangled by the platform's own resizer.

Can I resize many images at once?

Yes. Batch mode applies the same dimensions across a whole set and returns everything in one ZIP, which turns a fifty-image chore into one pass.

Will resizing reduce my image quality?

Downsizing is safe and often improves apparent sharpness; enlarging beyond the original stretches detail thin. If you need bigger, use our AI Image Upscaler, which reconstructs detail rather than stretching it.

Are my images uploaded during resizing?

No. Everything is processed in your browser, so photos never leave your device and big batches start instantly.
