Compress images before uploading them to a website
Photos straight from a phone or camera are often several megabytes each. Placed on a website or online shop, they slow pages down, especially on mobile data, and use up hosting storage.
Compress image reduces file size while keeping the picture looking natural. It runs in your browser, and you can compress a whole batch at once.
Page speed affects how visitors experience a site, particularly on phones and slower connections, and images are usually the largest part of a page. Compressing before upload is the simplest improvement because it needs no changes to the site itself. Give each file a descriptive name, such as blue-linen-shirt.jpg rather than IMG_4821.jpg, and add alt text in your website editor so the image is understandable to everyone. Re-check a few pages on your phone after uploading to confirm the photos still look sharp.
Step by step
- Open Compress image and add the photos you plan to upload.
- Choose a quality level; medium suits most web photos.
- Compress and compare the new sizes shown for each image.
- Download them and upload the smaller files to your site.
Tips
- Resize very large photos to the width your site actually displays before compressing.
- For an extra saving, convert JPG photos to WebP, which most modern browsers support.
- Keep originals for printing; web versions are for screens.
Questions
- How small should web images be?
- As a rough guide, aim for a few hundred kilobytes or less for a full-width photo.
- Will customers notice lower quality?
- At medium quality most photos look the same on screen while being much smaller.
- Are images uploaded to Convertora?
- No. Compression happens in your browser.
