Image Compressor

Shrink photos to fit upload limits without turning them into mush. This free compressor reduces JPG and PNG file sizes dramatically while keeping them sharp at normal viewing sizes — tuned for job portals, visa forms, WhatsApp sharing and fast websites.

Drag in a photo, pick a quality level, watch the live size preview, and download. Because compression runs on your device, originals stay private and batch work finishes in seconds.

Understanding Image Compressor

JPEG compression works by discarding visual detail humans barely notice — at 70–80% quality, files shrink to roughly a tenth with no visible difference on phones and screens. The trick is stopping before artifacts appear: smooth skies and faces show damage first, which is why the live preview matters more than any fixed setting.

PNG screenshots compress differently (lossless palette reduction). For photos use JPG output; for graphics with text keep PNG. Pair with Image Resizer first when dimensions also exceed requirements — fewer pixels compress further.

Pro Tips for Best Results

Compress copies, keep originals backed up — compression is one-way.
Resize dimensions before compressing for the smallest files.
Zoom the preview to 100% to judge real sharpness.
For documents, convert the compressed image to PDF afterwards.

Frequently Asked Questions

What quality setting should I use?

75–80% for photos heading to portals or WhatsApp; 85–90% when quality matters most (printing, portfolios). Below 60% only for tiny thumbnails.

Will compressed photos still print well?

For standard 4×6 prints, a well-compressed 1–2 MB file prints beautifully. For large enlargements, keep the original untouched.

Are my photos uploaded?

No — compression uses the Canvas API on your device. Your photos never cross the network.

Portal needs under 100 KB. Possible?

Usually yes: resize dimensions down first with Image Resizer, then compress at 70%. Text-heavy scans may need lower dimensions to hit tiny caps.

JPG or PNG output?

Photos: JPG. Screenshots, logos, text graphics: PNG. The tool picks sensibly based on your input.
