Resizing in your browser…
Your file never leaves this device
Rollphy Pro lifts the file limit and unlocks batch mode.
Every platform wants a different size: Instagram posts at 1080×1080, Stories and TikTok at 1080×1920, X posts at 1600×900, Facebook link previews at 1200×630, Pinterest pins at 1000×1500. Rollphy resizes your picture to fit any of these presets right in your browser — the image never leaves your device.
Pick a preset and drop your image: it is fitted inside the target box with the aspect ratio preserved, so nothing gets stretched or cropped away. High-quality resampling (the same smoothing your browser uses to render photos) keeps downscaled images crisp rather than mushy.
If your source is smaller than the preset, it is kept at its original size instead of being blown up with interpolation artifacts — upscaling never adds detail, so we don’t pretend it does. You can switch presets after resizing and download the version you need.
Frequently asked questions
- Will resizing crop my photo?
- No. Your image is fitted inside the chosen size with its aspect ratio intact — a 4:3 photo resized for Instagram Post stays 4:3 (1080×810), just within the 1080×1080 box.
- Which social media sizes are included?
- Instagram post, portrait and story, TikTok, Snapchat, WhatsApp profile, X (Twitter) post, Facebook link preview, YouTube thumbnail, Pinterest pin and LinkedIn banner. If you need another size, tell us — presets are one line to add.
- Can I resize more than one image at a time?
- Batch resizing is part of Rollphy Pro. The single-image tool on this page is free and unlimited.
