How to Compress Website Images Before You Upload Them
Prepare article images at the size a reader will actually see, then reduce unnecessary file weight before they reach your CMS. LoopIn Image Compressor lets you reduce file weight with quality, maximum-dimension, and output-format choices directly in the browser. The selected image stays on your device during processing, so you can make a practical web copy without creating a LoopIn account.
Start with the destination, not the source file
Use the original image as your backup, make a copy for the page, and compare the compressed result at the final display size. A 4000-pixel photo does not need to remain that large for a narrow article column. Before changing any setting, write down where the image will be used and how large it will appear there. That small decision keeps the export tied to a real reader, customer, client, or collaborator instead of an arbitrary number.
Use a repeatable review routine
Make one test export first. Open the saved file, compare it with the source at normal viewing size, and check the parts that carry meaning. Check fine lettering, skin tones, product edges, and smooth colour gradients. Those areas reveal excessive compression earlier than a general thumbnail view. If the image is part of a page, place the test version in the actual layout before processing the rest of the batch.
A simple browser workflow
- Select a small representative group of JPG, PNG, or WebP images.
- Choose a sensible maximum dimension, output format, and quality level for the destination.
- Process the files and review the result cards for dimensions, format, and file size.
- Keep the original source in a separate folder and download only the reviewed web copies.
Quality is more important than a dramatic percentage
The useful result is smaller files that are still useful at the intended viewing size. A smaller number can be helpful, but it is not the goal by itself. Avoid repeatedly saving the same JPEG. Start from the original each time so artefacts do not accumulate across multiple edits. When you test carefully once, you can reuse the same approach for similar assets and spend less time correcting uploads later.
Use the result where it creates real value
Prepared images can make a page, email, client handoff, form, or social post easier to use. Review the final upload after the destination platform applies its own handling, because that last step can change dimensions or compression again. Keep the original source for future formats, print work, and re-edits.
