How it works

From source files to finished batch

01

Choose your source images

Select images to open jpeg compressor in the studio. The matching workflow and preset are selected automatically; you can still change them before export.

02

Review the preset

The balanced preset starts at 82% quality. Review edges, faces, and text in the live preview before lowering quality further. Set a KB target when an upload form imposes a limit.

03

Process and save copies

Preview the selected image, then process the whole batch. Compare the real dimensions and encoded size before saving individual results or one ZIP. Your originals are not overwritten.

Common uses

Built for everyday image work

A focused compress workflow

Reduce JPEG photo file sizes with adjustable quality, an optional long-edge limit, and batch ZIP export. Originals remain untouched.

One image or a whole folder

Use the same settings across up to 50 files. Check unusual compositions or mixed-resolution images before processing the batch.

Combine with other edits

Add resize, crop, rotate, color, watermark, or compression steps in the studio. The workflow runs in the displayed order and shares one final output format.

Worth knowing

Keep the output predictable

Choosing the right settings

The balanced preset starts at 82% quality. Review edges, faces, and text in the live preview before lowering quality further. Set a KB target when an upload form imposes a limit.

Format and quality limits

JPEG is lossy and has no transparency. Repeated JPEG saves can degrade detail; import your original rather than an already compressed export.

Local processing and source limits

Files stay in browser memory. Each source can be up to 40 MB, within the 16,384-pixel edge and 80-megapixel canvas limits. HEIC uses the first contained image; AVIF requires browser decoding. Export is JPEG, PNG, or WebP, not HEIC or AVIF.

JPEG Compressor questions

How do I use jpeg compressor?

What should I check before downloading jpeg compressor results?

JPEG is lossy and has no transparency. Repeated JPEG saves can degrade detail; import your original rather than an already compressed export.

Does choosing images upload them?

No. The editor decodes and processes image files on your device. It loads its code from this website, but does not send your image contents to an image-processing service.
