No, files are NOT stored. They are deleted immediately after conversion and archive download. Complete privacy.

WebP is a modern format that reduces file size by 30-70%

What is AVIF and why use it?

AVIF is a modern image format based on AV1 codec. Provides better compression than WebP and JPG (30-50% smaller size with same quality). Supports transparency, HDR and animation. Supported in all modern browsers: Chrome 85+, Firefox 92+, Safari 16+.

Compress Image Online — Reduce File Size, Keep Quality

How to compress an image without losing quality

Compression reduces file size by re-encoding at an optimal quality level. The tool balances both sides: it removes unnecessary bytes while keeping detail, edges and colour. Unlike a blunt quality drop, you choose the degree and see the result.

For photos, quality 70–85% is usually enough: the file becomes 2–5× lighter and the difference on screen is almost invisible. For graphics with text and sharp edges, start at 85–90%.

Compress images for websites, marketplaces and email

For websites. Heavy images slow pages down and hurt Core Web Vitals. Compressing by 60–80% speeds up pages with no visible loss.

For marketplaces. Platforms limit image weight and dimensions — compression helps you fit the requirements.

For email and messengers. A 10–20 MB photo will not pass as an attachment; after compression it sends without trouble.

Supported formats

JPG, PNG, WebP, AVIF, HEIC, TIFF, BMP, GIF, TGA, JP2 and more. The output keeps the source format — you compress the file rather than convert it. If you need another format, use the converter.

How to compress an image online — step by step

1. Upload a file — drag it in or pick it from your device.

2. Choose the quality: lower means a smaller file, higher keeps more detail.

3. Press Process and download the result. No registration and no watermarks.

Compression tips

Start from the original, not an already-compressed copy: repeated re-encoding accumulates artefacts. Use PNG or lossless WebP for screenshots and text, JPG or WebP for photos. If you need an exact file size, compress, check the size and repeat with different quality if needed.

❓ Frequently Asked Questions

How do I compress a photo without losing quality?

Truly lossless compression (PNG or lossless WebP) gives only modest savings. For photos, compressing at quality 70–85% makes the file 2–5× lighter with almost no visible difference on screen.

Is compression free?

Yes. The service is free, with no registration and no watermarks. You can process up to 10 files at once.

Does compression reduce image resolution?

No. Compression changes only the file size and encoding quality; width and height stay the same. To change dimensions, use the Resize Image tool.

How much smaller can the file get?

Typically 2–5× for photos and up to 10× for PNGs with large flat areas. The exact result depends on the content.

Which formats are supported?

JPG, PNG, WebP, AVIF, HEIC, TIFF, BMP, GIF, TGA, JP2 and more. The output keeps the source format.

Is it safe to upload my photos?

Yes. Files are processed on the server and deleted automatically after the result is downloaded.

Can I compress several photos at once?

Yes, up to 10 files at a time. Results are downloaded as a single archive.

What is best for a website: JPG, WebP or AVIF?

WebP and AVIF give a smaller size at the same quality. Start with WebP — every modern browser supports it.
