Aspect Ratio Conversion with Clean Framing
Pick a preset or build a custom ratio and keep composition balanced without distortion.
Popular Ratio Presets
Switch to common ratios like 16:9, 1:1, 4:5, and 9:16 for posts, covers, and previews without doing manual calculations or breaking layout consistency.
Custom Ratio Builder
Enter your own width and height values to match unique layouts, product mockups, or print frames, with instant updates so unusual sizes export cleanly.
Smart Framing Preview
View the crop and output size together so faces, logos, and text stay inside the safe area before you export, avoiding trimmed edges or cut-off captions.
Resolution Control
Set the exact pixel dimensions for the new ratio so the file fits your layout while staying sharp on screen or in print for slides, banners, and proofs.
Format Options
Export JPG for broad compatibility or WebP for smaller files. Compare both outputs at the same ratio and keep the cleanest option for your audience.
Local, Private Processing
Everything runs in your browser, so images never upload. This keeps client assets private and makes retries fast when you test multiple ratios for reviews.

Aspect Ratio Conversion FAQ
Answers about ratios, cropping, and export quality.
Use 1:1 for square feeds, 4:5 for portrait posts, and 9:16 for stories or reels. 16:9 works for thumbnails and slides. If you are unsure, start with the platform's recommended size and test a preview for safe margins.
The tool adjusts the frame to the new shape, which may crop edges when the ratio is different. Use the preview and adjust output dimensions to keep important details inside the visible area before export. If needed, try a wider ratio.
Yes. Select Custom and enter width and height values. The preview updates immediately, so you can see the new framing and fine tune the ratio before downloading. Use whole numbers like 5:7 or 11:14 for quick setup.
Quality depends on the output size and format. Keeping a similar pixel count preserves detail. If you reduce dimensions, detail decreases slightly, so choose a size that balances clarity and file weight for the destination.
Stories and full-screen vertical posts use 9:16. Export at a vertical size like 1080x1920 to fill the screen while keeping text and faces centered within safe margins. Leave room for top and bottom UI overlays and stickers.
Use the preview to check the crop area before downloading. If elements are too close to the edge, increase the output size or switch to a ratio that gives more breathing room. This keeps branding readable across placements.
Yes. Choose JPG for broad compatibility or WebP for smaller files. You can export both and compare quality for the same ratio without reuploading, since format changes do not affect the ratio itself on the same image.
