A PRACTICAL IMAGE GUIDE

Image compression: smaller files, informed choices

Image compression reduces the bytes needed to store or send a picture. The right setting depends on whether you are sharing a photograph, publishing a transparent graphic, or fitting an upload limit. Start with Smart, then compare the result with your original.

Lossy or lossless?

JPEG, WebP and AVIF use quality-based encoding in this tool. Lower quality can save more space but may soften detail or create artifacts. PNG and TIFF use lossless encoding; metadata removal and resizing are separate operations. A resized image has fewer pixels even when its output encoding is lossless.

Compression, conversion and resizing

Compression changes how image data is stored. Conversion changes the file format. Resizing changes pixel dimensions. For a website, first choose dimensions appropriate for the space where the image will appear, then try JPEG or WebP for photos and PNG for graphics that need transparency.

Batch compression without an account

Choose up to 20 images of up to 10 MB each in the free workflow. Each file gets its own measured result and download. A failed image does not prevent successful files from downloading. ZIP packages the finished files together; it does not promise an additional reduction in already-compressed images.

Where processing happens

Your browser sends images to this service for processing and receives the results. The application does not store an image library or log image names. This is server processing, not a browser-only compressor. Keep your originals and download the results you want before closing the tab.

GOOD TO KNOW

Image compression questions

Understand the result before choosing your download.

Can I compress images without losing quality?

PNG and TIFF use lossless encoding here, but the amount saved depends on the original file. JPEG, WebP and AVIF use lossy encoding with adjustable quality. Compare fine text, edges and gradients rather than assuming every result looks identical.

Which image formats are supported?

Upload JPEG/JPG, PNG, WebP, AVIF, HEIC/HEIF, GIF, TIFF, BMP or ICO. HEIC exports to JPG by default. Keep GIF or WebP output for animation and TIFF output for TIFF pages. Other multi-frame conversions use the first frame or page and show a notice.

How do I reduce an image to 20 KB, 50 KB or 100 KB?

Use a target-size tool, choose JPEG or WebP when appropriate, and compare the measured result. Lowering quality may not reach a small target. You can enter smaller maximum dimensions and recompress, but the tool never resizes automatically to force a target.

Why is the compressed file larger?

A source image may already use efficient encoding. Another format, encoder or metadata setting can produce a larger file. The results show actual sizes and disclose larger outputs; try another format or smaller dimensions.

Can I use this for a website, email or upload form?

Yes. Check the required format, pixel dimensions and maximum byte size for your destination. A size reduction does not certify that an image meets every form, identity-photo or publishing requirement.
