Image Compressor: Shrink JPG, PNG and WebP Files
Large product photos, often 3 to 5 MB straight from a phone, make category pages load slowly and hurt mobile sales. Image Compressor shrinks JPG, PNG and WebP files directly in your browser, so your files never leave your device. By setting quality between 80 and 65 percent, you can reduce a 3.8 MB photo at 4000 pixels wide to about 350 KB at 1600 pixels. Back up originals first and inspect text at full zoom before publishing.
Step by step
- Open the tool in your browser and start with a JPG or WebP under 5 MB.
- Drag the file in; if width is above 3000 pixels, resize it to 1600 pixels.
- Set quality to 80 percent first and inspect texture and label text in the preview.
- If size is still above 400 KB, lower quality to 65 percent and export again.
- Rename as product-code-small.jpg and open it next to the original for a final check.
Example scenario
A jewelry seller had a 4032 by 3024 necklace photo weighing 4.2 MB that slowed her product page. She resized width to 1400 pixels and set quality to 72 percent. The file dropped to 380 KB and the mobile page loaded in about three seconds. She kept the original in an archive folder and used the smaller copy for the storefront.
Check your result
Open the compressed file at full zoom; label text should look sharp. Confirm the file is between 200 and 500 KB and width is between 1200 and 1600 pixels. If you see blur or banding, raise quality by five points and export again. Keep the original until the upload form accepts the new file.
Frequently asked questions
What quality should I pick?
Use 75 to 80 percent for product photos. If small text stays readable and the file is under 400 KB, the setting is right.
Does PNG compression work as well as JPG?
Less. PNG is lossless, so a 2 MB graphic may drop to 1.6 MB. For photos, use JPG or WebP.
Are my files uploaded to a server?
No. The tool runs in your browser and files stay on your device.
Can I process many images?
Yes, handle them one by one with the same width and quality to keep the catalog consistent.
