Resize Image

Scale photos to the exact width a form, site or listing demands — aspect ratio preserved, processed entirely on your device.

Type the width you need, drop your images, download — each photo is scaled to that exact pixel width with the aspect ratio preserved and never upscaled beyond its original size. Output as JPG, PNG or WebP; iPhone HEIC works as input. High-quality smoothing, no upload, batches welcome.

01 — EXACT PIXELS
Forms and platforms ask for exact widths — 1200, 1080, 800. Type the number once and every dropped photo comes out at it.
02 — NO UPSCALING
A photo smaller than your target stays at its native size instead of being blurred upward — a silent quality killer other resizers commit.
03 — PRIVATE
ID photos, documents and listings resize on your device. Nothing is uploaded, retained or logged.

How to use

  1. Drop your file(s) into the box above — or click it to browse.
  2. Conversion starts immediately; the tabs switch to a different output format. Adjust the quality slider to re-encode instantly.
  3. Click Download on each finished file — or Download all (.zip) for a batch. Nothing was uploaded at any point.

Why width-based resizing covers almost everything

Nearly every real-world requirement is a width: content images at 1200 px, marketplace photos at 1080, e-mail signatures at 600, avatars at 400. Height follows from the aspect ratio — forcing both dimensions is how photos get stretched. This tool takes one number, scales with high-quality smoothing, and refuses to upscale: enlargement can't add detail, only blur, so a smaller-than-target photo passes through at native size (the status line shows the real output dimensions).

Pick the output format by destination: JPG for general use, PNG when transparency or crisp graphics matter, WebP for your own site. Shrinking pixel count is also the single most effective compression step — for finer size control afterwards, the compressor adds a live quality slider.

When NOT to resize

  • To make an image bigger — upscaling manufactures blur, not detail; this tool deliberately won't do it.
  • Before further editing — edit at full resolution and resize as the last step.
  • When cropping is what you mean — resizing keeps the whole frame; if you need a square or circle, crop instead.

Frequently asked questions

Can I set an exact height instead?

Width is the control; height follows the aspect ratio to prevent distortion. For a fixed height, compute the matching width (height × aspect) — or crop first to the shape you need.

What happens to a photo narrower than my width?

It passes through at its native size — upscaling is refused by design, and the status line shows the actual output dimensions so nothing happens silently.

Does resizing reduce file size too?

Dramatically — pixel count is the biggest size factor. A 4032px photo resized to 1200px typically drops ~85% before any quality reduction.
