What is an Bild compressor?
An Bild compressor shrinks the file size of a picture so it loads faster, uploads quicker, and takes up less storage. The trade-off is controlled by quality: a lower quality setting discards more fine detail but produces a much smaller file, while a higher setting keeps the Bild looking nearly identical to the original. A good rule of thumb is to lower quality step by step until the Bild still looks great — most photos look fine at 60–80% quality.
This free online Bild compressor works on JPG, PNG, and WebP files and lets you pick the exact quality with a simple slider. It runs entirely in your browser, so your photos are never uploaded to a server — which makes it safe for private or sensitive Bilder. Whether you need smaller Bilder for a website, an email attachment, or a social post, you can reduce Bild file size in seconds, without installing anything.

Frequently asked questions
How much can I compress an Bild?
Reductions of 50–80% are typical for photos, depending on the source Bild and the quality you choose. The results list shows the exact before and after size for every file.
Does compressing reduce Bild quality?
Lower quality settings create smaller files but discard some detail, so very low values can soften an Bild. The slider is a preview of that trade-off, and quality down to around 70% is usually hard to tell apart from the original.
Can I compress multiple Bilder at once?
Yes — drop as many JPG, PNG, or WebP files as you need. Every file is compressed with the same quality setting and each result can be downloaded individually.
Are my Bilder uploaded to a server?
No. Komprimierenion happens locally in your browser, so your Bilder never leave your device — nothing is stored, tracked, or sent anywhere.
