Need to make a picture smaller for a form, larger for a print, or exactly 1080×1080 for Instagram? PIXLFLW resizes images to any dimensions right in your browser. Unlike most online resizers, your photo is never uploaded to a server — the whole tool runs locally on your device, so it works fast and keeps your pictures private.
What you can do
- Resize by pixels — enter exact width and height (e.g. 1920×1080) or change just one side and keep the aspect ratio.
- Resize by percent — scale a photo down to 50%, 25% or any ratio in one step.
- Print units — work in px, %, mm, in, handy for documents and printing.
- Reduce file size — smaller dimensions plus the JPG quality slider in the export dialog let you hit targets like «under 1 MB» or «under 50 KB».
- Keep quality — high-quality resampling avoids the blurry, jagged look of naive resizing.
How to resize an image
- Drop your picture into the upload area above (formats: GIF, JPG, BMP, PNG, WEBP, HEIC, TIFF).
- The editor opens with a resize step already added — type the target width, height or percentage.
- Preview the result, then download it as JPG, PNG or GIF.
Resizing without losing quality
Scaling a photo down is effectively lossless: PIXLFLW resamples with smoothing, so a smaller copy stays clean and sharp. Scaling up cannot invent detail that the camera never captured — moderate enlargements (up to about 2×) hold together, beyond that edges soften. If the goal is a smaller file rather than smaller dimensions, resize first and then set the JPG quality on export, where a live size estimate is shown.
Changing the pixel dimensions of an image
Enter the exact pixel width and height you need — 1080×1080 for a square post, 1200×1200 for a marketplace listing, 1920×1080 for a slide or wallpaper, or a single side like 750 px for a web layout. Lock the aspect ratio to change one side and have the other follow, or unlock it to stretch to an exact frame. The pixel grid is rebuilt at the new size, so the exported file really is those dimensions — not a scaled preview.
Because editing is non-destructive, you can change the numbers as many times as you like — the original pixels are only resampled once, on export.
