I built AspectFit to do one job: fit your photos into social media sizes without cropping. Splits, watermarks, borders and batch exports are all in service of that. Everything runs in your browser, so your photos never leave your device.
Your entire image stays intact. AspectFit pads around it to fill the frame instead of cutting into it, and a slider scales the photo inside that frame until the spacing looks right.
Turn one wide photo into 2 or 3 swipeable slides. Drag and scale it across the full canvas to pick what lands where, and the background, blur and border run straight through the seams so the set reads as one continuous image. Downloads as a ZIP, already named in carousel order.
Start from a template or drop in your own logo. Position it, rotate it, tile it across the photo to deter reposts — then save up to 10 presets so your brand is one click away next time.
Posts, stories, reels and link cards for Instagram, Reddit, Facebook and X. Flip any preset to landscape with one tap, or keep your photo's original ratio.
Fill the padding with a solid color, a blurred version of your photo, or leave it transparent. Add a border on top — solid, dashed or dotted, any width, color and corner radius.
Drop a bunch of photos at once, apply the same settings to all of them, and download everything as a ZIP. HEIC, AVIF, WEBP and TIFF go straight in — no converting first.
Exports render from your source image, not the preview. Scale down to 75, 50 or 25% for smaller files, or pick Instagram-optimized to land on the 1080px width Instagram publishes at.
Nothing gets uploaded anywhere. All the processing happens right here in your browser. I don't even have a server to store them on.
No account, no sign-up, no upload limits. Every change previews live as you make it.
