Everything here is written to answer one question: how do I make this image smaller without ruining it? Each guide is short, practical, and points at the tool that does the job.
Start with the task
- How to compress images for a website — the version that actually helps your Core Web Vitals.
- How to compress images for WordPress — sizing, formats and media library hygiene.
- Compressing listing images for Etsy, eBay and Amazon — satisfy the minimum resolution and the maximum file size at the same time.
- How to reduce image file size — the four levers, in the order that works.
- How to compress images for email attachments — get under the size limit the first time.
- How to compress an image to 200 KB (or 100 KB) — hitting a hard upload limit.
- How to compress photos on iPhone and Android — no app required.
- Why are my photos so large? — where the megabytes actually come from.
Format and quality questions
- Compress JPG without losing quality — what "quality 75" really costs you.
- Compress a PNG without losing quality — lossless means lossless, and what to do when it is not enough.
- How to resize an image without ruining it — pick the right size and keep the proportions.
- JPG vs PNG: which format should you use?
- JPG vs WebP: which is better for your website?
- WebP vs AVIF: which should you use?
- Image compression vs resizing — they are not the same thing, and mixing them up costs you quality.
Do it now
Compression and resizing both run in your browser on this site, so nothing you open is uploaded anywhere:
- Compress Image — one file, live before-and-after preview.
- Resize Image — set a maximum width or height.
- Crop Image — cut to a free selection or a fixed ratio like 1:1 or 16:9.
- Compress to Size — hit an exact limit such as 100 KB or 200 KB.
- Image Converter — switch between JPG, PNG and WebP, or make a PDF from images.
- Compress Multiple Images — a whole batch, downloaded as one ZIP.
