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.

How many photos can I put in one collage?

Anywhere from two to six images per collage. Drop them in, choose a column, row, or grid layout, and export the combined result.

Does the collage tool add watermarks?

No. Imagly is completely free — collages are exported clean, with no watermarks, no accounts, and no limits.

Is the collage maker really private?

Yes. All compositing happens inside your browser. Your photos are never uploaded or stored anywhere.

Can I compress a collage after making it?

Absolutely. Export your collage, then drop it into the compressor to trim the file size before publishing.

Collage

Combine two to six images into a clean column, row, or grid and export one crisp PNG without uploading anything.
