Compress JPG Photos to 500KB or 1MB
Phone photos are often 3MB to 10MB each, which is too big for many forms, marketplaces, and email attachments. With Reduce Photo Size you pick a target of 500KB or 1MB and compress a whole folder of photos at once.
Which target to pick
1MB or less keeps photos sharp enough for full-screen viewing and is a good default for blogs, listings, and email. 500KB or less is a good fit for upload forms with a strict cap or for pages that need to load fast on mobile.
If you are not sure, start with 1MB. If the site still rejects the file, run the same photos again with 500KB.
How to do it
The whole process takes a few clicks, and you can do it on a phone or a computer.
- Click "Add photos (up to 100)" or drag your photos in.
- Pick a Save format. Original format keeps PNG as PNG and WEBP as WEBP, and saves other photos as JPG.
- Under Target size, choose 1MB or less or 500KB or less.
- Optionally set Max width to 2560, 1920, 1280, 1080, or 800. Leave it at Original size if you want full resolution.
- Click Compress all. Save photos one by one, or click "Save all as ZIP".
- iPhone HEIC photos can be added directly. They are converted to JPG first.
- For more than 100 photos, save the first batch, then add the rest.
Reading the results
Each row shows the original size, the compressed size, and the percent saved. Below the list you see the total, for example 1.4MB to 271KB. When we tried the three sample photos, each 3000 x 2000 JPG went from about 470KB to about 90KB, roughly 80% smaller, with quality-based compression.
A PNG screenshot can sometimes get slightly bigger when it is saved again in the same format. The tool tells you when that happens. Switch the Save format to JPG or WEBP for those files.
By quality instead of a target
If you do not have a size limit, choose "By quality" and use the Quality slider. Around 80% is a common choice that keeps photos looking the same while cutting the size a lot.
Max width matters more than you might think. A 4000-pixel photo shown on a 1080-pixel phone screen wastes most of its pixels. Setting Max width to 1920 or 1280 often saves more than lowering quality.
Privacy
Photos are processed in your browser and are never uploaded. Location and device details (EXIF) are always removed from the saved copies, and your originals are not changed.
