Image Ratio Converter User Guide
This guide focuses on practical usage of the image ratio converter: which mode to choose, where each ratio works best, and how to export reliable outputs for real publishing workflows.
How to use this image ratio converter
Start by uploading one image, then pick a target ratio such as 1:1, 4:5, 16:9, or 9:16. Choose Crop when you want tighter framing, Pad when you want to keep all content, or Scale when you need a new size without changing shape. Preview updates in real time, so you can verify the result before download.
Best mode for each goal
Use Crop for feed posts where composition must look strong in limited space. Use Pad for product photos, certificates, and logos when no content should be cut. Use Scale for simple pixel resizing when a platform requests exact dimensions but the original ratio should stay intact.
Use case: social media repurposing
A common workflow is turning one master image into multiple social formats. With this image ratio converter, you can export 1:1 for profile grids, 4:5 for feed posts, and 9:16 for stories or short videos in one session. This saves time and keeps branding consistent across channels.
Use case: e-commerce listings
Marketplaces often require square thumbnails while your source is horizontal. Select 1:1 and Pad to keep the product fully visible, then export PNG or JPG. This image ratio converter helps you standardize catalog images without manually editing each item.
Use case: ad creatives and landing headers
Paid campaigns usually need several banner sizes. Use Crop for hero-focused variants and Scale for exact pixel requests from ad managers. This image ratio converter is useful for performance teams that need to ship many size variants quickly.
Quality and export tips
For transparent backgrounds, use PNG or WebP. For lightweight distribution, use JPG with quality around 0.85 to 0.92. If your image contains small text or thin lines, keep a larger output width first, then downscale only when required by the destination platform.
Privacy and workflow confidence
This image ratio converter runs locally in your browser, which means your files are not uploaded to a remote conversion API. Teams can use it for everyday production with fewer privacy concerns and faster turnaround for internal review and final delivery.
Quick example: from one image to three outputs
Example workflow: upload a 2400x1600 source, export 1080x1080 for product cards, 1080x1350 for Instagram feed, and 1080x1920 for story placement. This image ratio converter lets you switch ratio and mode quickly while keeping output naming and dimensions easy to track.
FAQ
What is aspect ratio?
Aspect ratio is the relationship between width and height, such as 1:1 or 16:9.
Crop vs Pad: what's the difference?
Crop removes parts of the image to fit ratio; Pad keeps all content and adds background space.
How do I make Instagram or TikTok sizes?
Pick preset ratios like 4:5, 1:1, or 9:16, then adjust output width if needed.
Is my image uploaded?
No. All image processing runs locally in your browser.
Why is exported size different?
Output dimensions depend on selected mode, ratio, and width/height settings.
