Free Image Compressor
Reduce image file size up to 80% without losing quality
About this tool
Convertit's Image Compressor reduces image file size while keeping the result visually useful for websites, email, forms and social uploads. Large photos and screenshots can slow down pages, fail upload limits and make sharing harder. Compression helps you keep the same image dimensions with a smaller file size.
The tool is useful for bloggers, store owners, students, marketers, developers and anyone preparing images for online use. Upload a JPG, PNG or WebP image, choose a quality level, and download the optimized result after processing.
Image compression is especially important for SEO and page speed. Smaller images load faster, use less bandwidth and create a smoother experience on mobile networks. For most photos, a moderate quality setting can reduce size significantly without an obvious visual difference.
How to use Image Compressor
- Upload the JPG, PNG or WebP image you want to compress.
- Choose a compression quality level. Lower values create smaller files; higher values preserve more detail.
- Start compression and wait for the result.
- Download the optimized image and compare it with the original before publishing.
- Add the file, text or link you want to process.
When to Compress Images
Compress images before uploading them to a website, ecommerce product page, blog post, CMS, email campaign, job application or form with strict file limits. It is also helpful when sending photos over slow connections or keeping a portfolio lightweight.
For website images, compression should usually happen before upload rather than after the page is already slow. Keeping assets small from the start improves performance and avoids repeated cleanup work later.
Choosing the Right Quality
A quality range around 70-85 works well for most web photos. Use a higher setting for product photography, portfolios or detailed visuals where quality matters. Use a lower setting for thumbnails, previews or images where file size is more important than perfect sharpness.
PNG images behave differently from JPG because PNG is often used for sharp graphics, transparency and screenshots. If a PNG remains large after compression, consider converting it to WebP or JPG when transparency is not required.
