JPG Size Reducer
Shrink a JPG or JPEG photo's file size — use a quality slider or hit an exact KB target.
Reduce JPG Size Online
This JPG size reducer shrinks JPG and JPEG photos using the same quality-based compression browsers and cameras already use for that format, so there's no format conversion involved — your file stays a JPG throughout. Upload a photo, then either drag the quality slider or switch to "Compress to Size" for an exact KB target like 50KB or 100KB.
How to Reduce a JPG's Size
- Upload your JPG — Click Upload Image or drag a JPG/JPEG file into the box above.
- Pick a compression method — Use the quality slider for a quick reduction, or "Compress to Size" for an exact KB target.
- Compress the image — The tool re-encodes the JPG at the right quality level to hit your target.
- Download the result — Check the new file size, then click Go to Download.
Why Reduce a JPG's File Size?
JPGs from modern phones and cameras are often several megabytes — far larger than most forms, emails or websites need. Reducing a JPG's size helps with:
- Form and portal uploads — many Indian exam, ID and government portals cap uploads well under 1MB.
- Faster emails and messaging — smaller JPGs attach and send faster, especially several at once.
- Website performance — smaller JPGs mean faster-loading pages for anyone building a site or blog.
Supported Image Formats
Upload JPG, JPEG or PNG (most other common image formats will also open). The result is delivered as an optimized JPEG, which compresses photographic images far more efficiently than PNG — if you specifically need to keep a PNG's transparency, use Convert Image instead.
Photo Quality After Compression
JPG compression is lossy by design — some fine detail is traded for a smaller file. At moderate quality (roughly 70-85%), most people can't spot the difference at normal viewing sizes; pushing to a very small KB target (like 20-50KB) will show more visible softening, especially on busy or high-detail photos.
Frequently asked questions
Does this change my JPG to another format?
No — JPG stays JPG. The tool re-encodes it at a lower quality level to reduce file size; nothing is converted.
Can I target an exact file size, like 100KB?
Yes — switch to "Compress to Size" and enter your target in KB; the tool searches for the highest quality that still fits.
Will this work on a JPEG from my phone?
Yes — most phone photos are already JPEG, so this is one of the most common use cases for this tool.
Is compression done on a server?
No, everything happens locally in your browser using the Canvas API — your file is never uploaded.
What if I need a specific KB size like 20KB or 50KB?
