Are my images uploaded to a server?

No. Imagly works entirely client-side. Your images are decoded and re-encoded by web workers inside your browser, and the compressed results never leave your device.

Which image formats are supported?

Imagly supports all major image formats: JPEG, PNG, WebP, AVIF, GIF, SVG, BMP, ICO, and TIFF up to 50 MB each, in batches of up to 30 files.

What does the auto output format do?

The auto option keeps each image in its optimal compatible format. Choose JPEG, PNG, WebP, or AVIF explicitly when you want to convert files across formats.

What is smart compression?

Smart compression targets a file-size budget you set, for example 1 MB. The encoder iterates internally, gradually lowering quality until the image fits within the target size.

Can I resize images at the same time?

Yes. Pick a maximum edge length such as 2048 px and the longest side of every image is scaled down before compression, which makes results dramatically smaller.

Is Imagly free to use?

Yes, Imagly is free for any use with no account required. There are no watermarks, no usage limits, and no image is ever uploaded anywhere.

How many files can I compress at once?

Batches support up to 30 images with a 50 MB limit per file. Each file is processed in parallel with its own live progress bar, so the page stays responsive even with a full queue, and you can download everything bundled into a single ZIP.

Will compression reduce my image quality?

Compression is always a size-versus-fidelity tradeoff, and you control both ends. The quality slider runs from 10 to 100, with values around 80 usually looking visually identical while cutting size dramatically. Alternatively, use smart compression to target an exact file size, or cap the longest edge from 640 to 2560 px to shrink photos dramatically with minimal perceived loss.

Will enlarged images look pixelated or blocky?

Imagly uses smooth interpolation, so instead of harsh blown-up pixels the edges stay soft and natural. It is ideal for small images and screenshots.

By how much can I enlarge an image?

Up to 3× the original dimensions. A 400 px image becomes 1200 px wide without changing its crispness beyond smooth interpolation.

Why does my enlarged image have a bigger file size?

Enlarging increases pixel count, and more pixels mean more data. Push the result through the compressor tool afterward to shrink the file size.

Does the enlarge tool upload my image?

No. Enlarging is done entirely in your browser with web workers, so the image never leaves your device.
