How to Reduce Image File Size Without Losing Too Much Quality
A practical image compression workflow for smaller files that still look clean.
By Berlvis Editorial Team · Published · Updated
Start with dimensions
Large photos often have more pixels than you need. Resize the image to a sensible width before compressing. A smaller image at good quality usually looks better than a huge image compressed too aggressively.
Pick the right format
Use JPG or WebP for photos, PNG for screenshots and sharp graphics, and keep the original file if you may need to edit it later. For upload forms, check whether the site requires a specific file type.
Review the important details
After compression, zoom into faces, numbers, ID details, logos, and small text. If those details are unclear, use a higher quality setting or resize less aggressively.
Match the image to its destination
A profile photo, website banner, product image, and scanned certificate have different needs. Find the destination's required dimensions, format, and maximum file size first. Resizing to the actual display dimensions often saves more space than lowering quality on an image that is still much larger than necessary.
Keep an original and compare outputs
Export reduced images as new files and retain the original until the upload or publication is complete. Compare both files at normal viewing size as well as at higher zoom. This makes it easier to choose the smallest version that still preserves the text, edges, colors, and subject detail that matter.
FAQ
What quality setting should I use?
Medium is a good starting point for most photos. Use higher quality when the image contains small text or official details.
