How do you compress an image without losing quality?
Compress an image by re-encoding it at 75–80% quality, which typically removes 60–70% of the file size with no difference visible at normal viewing size. Exporting to WebP instead of JPG saves a further 25–35%. Always compress from the original, because each JPG or WebP save discards detail permanently.

Reduce image file size by 50–80% while keeping them looking sharp. Smaller images mean faster pages, better Core Web Vitals scores and less bandwidth for your visitors.
How to use Compress Images Without Losing Quality
Upload your images — Drag one or more JPG, PNG or WebP files into the drop zone.
Set the quality level — Start around 75–80%. Most photographs show no visible difference there while losing most of their weight.
Check the comparison — Use the before/after slider to confirm details you care about survived.
Download — Save individual images, or grab everything as a ZIP.
Why use this tool
Quality you control — Move a single slider and see the size and preview update live, so you can stop exactly where the quality still looks right.
Batch processing — Compress an entire folder of images in one pass and download them together as a ZIP.
Side-by-side comparison — A drag slider overlays the original and compressed versions so you can judge the trade-off honestly.
Format conversion — Export to WebP for substantially smaller files on modern browsers.
Frequently asked questions
How much can I compress without it looking bad?
For photographs, 75–80% quality typically cuts file size by 60–70% with no difference visible at normal viewing size. Graphics with flat colour and sharp text need a higher setting, around 85–90%.
Should I use WebP instead of JPG?
For the web, usually yes — WebP is roughly 25–35% smaller than JPG at matching quality and is supported by every current browser. Keep JPG when a file needs to open in older desktop software.
Does compressing repeatedly degrade the image?
Yes, with JPG and WebP. Each save discards information permanently, so re-compressing an already-compressed file compounds the damage. Always start from the original.
Does this strip EXIF data?
Compression removes most metadata, including GPS coordinates and camera details. That is usually desirable before publishing photographs online.
Are my files uploaded to a server?
No. Every conversion runs inside your own browser using JavaScript and WebAssembly. Your files never leave your device, which means there is nothing for us to store, read, or leak.
