Features

Instant, right in your browser

The engine runs in your browser, so there is no progress bar and no queue. Type your numbers and the preview updates live.

Ratio lock you control

Keep proportions safe with the lock on, or unlock it to hit an exact non-proportional spec when a form demands one.

Pixel-exact output

Type a width and height and the download matches them exactly — to the pixel, every time, with no silent rounding.

Resize to exact pixels in three steps

  1. Drop your image

    Drag a file in, tap to pick one on your phone, or paste from the clipboard. The current pixel dimensions are shown right away.

  2. Type width and height

    Enter the exact pixel values you need. Leave the ratio locked to fill the other field automatically, or unlock it to set both sides independently.

  3. Download

    Click download and the resized copy saves at exactly the dimensions you typed. The original stays untouched on your device.

Jobs that need exact pixels

Hit a 1080×1080 social post

Instagram's square wants exactly 1080×1080. Type those numbers and download an image that fits the feed with no auto-crop chopping off the edges.

Size a 1200×628 link preview

Open Graph and Twitter cards render best at exactly 1200×628. Set the width and height and your shared link shows a crisp, correctly-framed thumbnail.

Match an email banner spec

Newsletter templates often specify a header at, say, 600×200 pixels. Hit the exact size so the banner lines up inside the layout without scaling artifacts.

Resize an ad to an exact slot

Display ad networks list precise sizes like 300×250 and 728×90. Type the slot dimensions and export an asset that drops straight into the placement.

Fit a marketplace photo to a fixed size

Some storefronts require an exact square such as 2000×2000. Set it once and every listing photo matches, so your gallery looks consistent.

Produce an icon at an exact resolution

App and favicon specs call for sizes like 512×512 or 192×192. Type the resolution and export a clean, correctly-sized icon in seconds.

When you need exact pixel dimensions

Plenty of resizers only offer a percentage slider or a vague “small / medium / large.” That is useless when a spec sheet says the image must be exactly 1200×628 pixels. Pixel-exact resizing is its own job: you have a target width and height in mind, and the output must match them to the pixel — no rounding, no surprises.

AnyResizer puts two number fields front and center. Type the width, type the height, and that is precisely what you download. Keep the aspect-ratio lock on and the second field fills itself to avoid distortion; turn it off when a spec demands an exact non-proportional size and you accept the stretch. A live preview shows the result before you commit.

Everything runs in your browser on a WebAssembly engine, so the image stays on your device and the resize is instant. Lanczos resampling keeps the downscaled result sharp, EXIF orientation is applied to the pixels, and you can read the current dimensions of any image you drop in case you are not sure where you are starting from.

Why resize by pixels here

  • Two clear number fields, no guessingWidth and height are the whole interface. Type, preview, download — no sliders to nudge or presets to decode.
  • See the starting dimensionsThe current pixel size of your image is displayed the moment you drop it, so you always know what you are working from.
  • Lock or break the aspect ratioProportional by default to avoid stretching, fully manual when a spec needs an exact non-proportional size.
  • Batch many files to one sizeDrop a folder, type the dimensions once, and every file lands at the same pixel size, zipped for download.

Tips for pixel-exact resizing

  1. Tip 1:

    Keep the aspect-ratio lock on unless a spec truly requires a non-proportional size — unlocking it stretches faces and logos in unflattering ways.

  2. Tip 2:

    Downscaling to exact pixels is clean; upscaling past the original resolution just stretches existing pixels and softens detail. Start from the largest source you have.

  3. Tip 3:

    If a platform crops your image anyway, it is matching its own ratio — set your pixels to that ratio first so nothing important gets cut.

  4. Tip 4:

    Not sure of your starting size? Drop the file and read the dimensions shown before you type new ones.

  5. Tip 5:

    For print, pixels are only half the story — divide by your target DPI to know the physical size, then resize to the pixel count that math gives you.

Resize image in pixels FAQ

How do I resize an image to an exact pixel size?

Drop your image, type the exact width and height in the two number fields, and click download. The output matches the pixel values you entered with no rounding.

Can I set width and height independently?

Yes. Turn off the aspect-ratio lock and you can type any width and any height. Leave it on and the second field fills automatically to keep the image from stretching.

How do I know my image's current dimensions?

They are displayed the moment you drop the file, so you always know the starting width and height before you type the new ones.

Will resizing by pixels distort my image?

Only if you unlock the aspect ratio and type a width and height that do not match the original proportions. With the lock on, the image scales cleanly with no distortion.

Is my image uploaded anywhere?

No. The resize runs in your browser with WebAssembly, so the file never leaves your device. You can confirm nothing is sent in your browser's Network panel.

Can I make an image larger by typing bigger pixel values?

You can, but enlarging past the original resolution stretches the pixels you already have and cannot add real detail. For best results, downscale from a larger source.

What units does it use — pixels or something else?

Pixels. The two fields are width and height in pixels. For print you would convert your target physical size and DPI into a pixel count and enter that.

Can I resize many images to the same pixel size at once?

Yes. Drop multiple files, type the dimensions once, and every image is resized to that exact size and downloaded as a ZIP.
