Compress Image Online
Shrink images for the web, email, social media or storage. Pick a quality preset, drag the slider, or set a target file size — everything runs locally in your browser, so your photos never leave your device.
Files never leave your device — 100% browser-based.
When to use this tool
- You're emailing photos and need to stay under the mailbox attachment limit.
- You're uploading to a website with a strict file-size cap.
- You're saving storage on a phone, Drive or website backup.
Best for
- Email attachments
- Forum and CMS uploads
- Free-tier cloud storage
- Slow networks
Quality & file size notes
- • Set a target file size (e.g. 500 KB or 1 MB) and the compressor will auto-tune quality to land as close as possible without going under.
- • For photos, JPG quality 75–85 saves most of the bytes with little visible difference. PNGs benefit most from being converted to JPG or WEBP.
Things to watch out for
- — Compression is one-way for lossy formats — keep your originals.
- — Heavy compression on portrait photos can soften skin texture. Compare before/after at 100% zoom.
Not sure which format to choose?
Compare JPG, PNG, WEBP, AVIF, HEIC, GIF, SVG, BMP, TIFF and PDF side-by-side with use cases and trade-offs.

How small can I make an image without it looking bad?+
A 5 MB phone photo usually compresses cleanly down to 500–800 KB. Pushing below 200 KB often requires resizing the dimensions too.
Does compression remove EXIF metadata?+
Yes — we re-encode the image, which strips camera and GPS metadata. That's good for privacy and also makes the file smaller.
Can I compress hundreds of images at once?+
Yes. Drop them all in, apply the same target size and download a single ZIP at the end.

Frequently asked questions
Quick answers about how this tool works.
Are my images uploaded anywhere?
No. All compression happens locally in your browser using the Canvas API. Your files never leave your device.
Is the compressor free?
Yes — fully free, unlimited, no account, no watermarks.
Will my image lose quality?
JPG, WEBP and AVIF use lossy compression, so some quality is traded for smaller files. Use the quality slider to find the sweet spot. PNG is lossless — most savings come from re-encoding and stripping metadata.
How small can I make my images?
Pick a target file size (in KB) and we'll auto-tune quality to get as close as possible while preserving the best look.
Is EXIF metadata removed?
Yes — re-encoding strips EXIF, GPS coordinates and camera tags, which also reduces file size.
Does it work on mobile?
Yes. The compressor is fully responsive and runs on any modern phone, tablet or desktop browser.
