JPG, PNG, WEBP, HEIC, AVIF, TIFF
Simple tool.
Does one thing well.
I built AspectFit to do one job — fit your photos into social media sizes without cropping. Everything runs in your browser, so your images stay on your device.
Keep Your Full Photo
Your entire image stays intact. AspectFit adds padding around it to fill the frame — nothing gets cut off.
Ready-Made Sizes
Square, portrait, story, reels — pick the size you need and your image is formatted instantly.
Pick Your Background
Fill the padding with a solid color, a blurred version of your photo, or keep it transparent.
Add Your Watermark
Drop in your logo or type some text. Adjust the size, position, and opacity until it looks right.
Batch Processing
Drop a bunch of photos at once. Apply the same settings to all of them, then download everything as a ZIP.
Your Photos Stay Private
Nothing gets uploaded anywhere. All the processing happens right here in your browser. I don't even have a server to store them on.
Full Quality Export
Your photos export at their original resolution. Adjust JPEG quality or switch to PNG — no compression surprises.
Resize Within the Frame
Use the slider to scale your image up or down inside the padded area until the spacing feels right.
Real-Time Preview
See changes as you make them. Adjust settings and the preview updates instantly — no waiting around.
Three steps.
That's it.
No accounts, no installs, no learning curve. Just drop your photos in and get them back sized for Instagram.
Drop Your Photos
Drag in one photo or a whole batch. Nothing gets uploaded — your images stay on your device.
Pick Your Settings
Choose a size (square, portrait, story), set your background, and adjust the fit.
Download
Save your images individually or grab them all as a ZIP. Full quality, ready to post.
