Prepare Product Images: Crop, Resize, Compress and Review
Prepare a batch of product photos with consistent framing, useful dimensions and an accepted format. Test one image before processing the collection.
How Image Compression Works
A smaller image file is easier to share, but not every kind of compression preserves the same detail. Here is how to choose a sensible setting and check the result.
JPG or PNG: Which Should You Choose?
Choose a format based on what is in the image and where you plan to use it. Photos, screenshots, and transparent logos have different needs.
WebP or JPG: Compare Size, Quality, and Compatibility
WebP can make web images smaller, while JPG remains useful for destinations that require it. Compare your own images before choosing.
How to Reduce an Image File Size
If an image is too large to upload or share, check its dimensions, choose a suitable format, and adjust quality. Review the result at each step.
Image Metadata: What to Check Before Sharing
An image can contain information beyond the visible picture. Learn what metadata may reveal, what removal changes, and how to check the file you share.
Choosing an Image Format for a Website
Start with the image content, the transparency you need, and what your publishing system accepts. Then compare size and appearance in the actual page.
Prepare Images for Social Media Without Stretching Them
Check the current requirements for the exact post type, choose a crop, then resize and compress. A feed image, story, and profile photo may need different shapes.
Process Several Images With the Same Settings
Apply a shared operation to several images, then review each result. Batch processing saves repeated steps, while individual editing is better when every photo needs different treatment.
