One photo, the right size for every platform
Each network wants a different shape: a square or 4:5 post for Instagram, 9:16 for stories and Reels, a wide 1500 × 500 header on X, a thin 1584 × 396 banner on LinkedIn, a 1280 × 720 thumbnail on YouTube. Drop a photo once, tick the sizes you need, and download them all together — cropped where you choose, or fitted whole on a blurred or solid background. Everything happens in your browser; the photo is never uploaded.

- 3Choose how the photo fills each shape: Crop to fill, Fit + blur or Fit + colour. When cropping, move the focus sliders to keep the important part in frame.

Crop, or fit the whole picture
Crop to fill fills the shape edge to edge and trims what does not fit. The focus sliders choose which part survives: slide horizontally to keep a face on the left of a group photo, vertically to keep a horizon or a headline.
Fit + blur keeps the entire photo and fills the empty space with a blurred, enlarged copy of it — the look platforms use for a landscape video in a portrait frame. Fit + colour does the same on a solid colour of your choice, which suits logos and product shots on white.
Private, and nothing to install
The photo is decoded and drawn in your browser, and every size is rendered on your device. There is no upload, no account and no watermark.
For an exact pixel size or a file-size limit such as 100 KB, use the image resizer. To put several photos in one post, use the collage maker; to add a caption, the meme generator.
Frequently asked questions
- What size should an Instagram post be?
- 1080 × 1080 pixels for a square post, 1080 × 1350 for a portrait 4:5 post — which takes up the most room in the feed — and 1080 × 566 for landscape. Stories and Reels are 1080 × 1920.
- What is the YouTube thumbnail size?
- 1280 × 720 pixels, a 16:9 ratio, under 2 MB. Saving as JPEG at quality 85–90 keeps it well below the limit.
- Can I resize one photo for several platforms at once?
- Yes. Tick every size you need; each one is previewed, and they all download together as a single ZIP.
- How do I avoid cutting off part of my photo?
- Choose Fit + blur or Fit + colour. The whole photo is kept and the rest of the shape is filled with a blurred copy or a solid colour.
- Does it add a watermark?
- No. The images are yours, with no watermark and no sign-up.
- Is my photo uploaded?
- No. Every size is rendered in your browser and the photo never leaves your device.
