Low
Reduces size with minimal changes. For PNG the compression is lossless: the pixels stay identical. Use it for product photos, portfolios or images you'll print.

Lighter photos that don't look worse
A photo taken with a modern phone can weigh 3 to 8 MB. That's more than you need for almost anything: a form that only accepts 1 MB, an online store that gets slow, an email with ten photos that won't send. Compressing the image removes information the eye can't tell apart and reduces the size considerably.
SoloHazlo keeps each file's original format: a JPG stays a JPG and a PNG stays a PNG. When it's done we show you the size before and after, and if an image was already so optimized that it can't get smaller, you get it back as is so it never ends up bigger.
What each compression level does
Recommended
The ideal balance between quality and size. In most photos you can't see the difference and the file ends up much lighter. It's the best option for the web, social media and email.
High
Prioritizes size. Besides compressing more, it scales very large images down to a maximum of 2560 pixels per side. Ideal for forms with strict limits or for sending lots of photos.
Photo data
At every level, hidden camera data (such as phone model or GPS location) is removed, since it takes up space and can reveal personal information.
How to compress images with SoloHazlo
Upload your images
Select them or drag them into the box. You can compress up to 20 at once, up to 25 MB each.
Choose the level
If you're not sure, leave "Recommended". If it's still too big after compressing, try again with "High".
Check and download
You'll see the original size, the final size and the reduction percentage. One image downloads directly; several come in a ZIP.
How big should an image be?
There's no single number, but these guidelines help you know when it's small enough:
Websites and online stores: 100 to 300 KB per photo is a good target. Heavier images make your page load slowly, especially on mobile data.
Forms and applications: check the limit the platform shows; it's usually between 500 KB and 2 MB. The recommended level is almost always enough.
Email: if you send lots of photos, compressing them keeps you under the attachment limit and gets the message there faster.
Printing: use the low level or keep the original; for printing, resolution matters more than file size.
Common problems and how to fix them
The reduction was 0%
That image was already highly optimized and compressing it again would make it bigger, so it's returned unchanged. Try the "High" level if you really need to shrink it.
My PNG lost some shades
At the recommended and high levels, PNGs are reduced to a color palette, which works very well for logos, screenshots and illustrations. In photos with gradients it may show: use the low level or convert it to JPG with Convert images.
My photos are iPhone HEIC files
First convert them to JPG with Convert images; the result already has a reasonable size and, if needed, you can compress it here.
I need to compress a PDF, not an image
For documents use Compress PDF, which optimizes the images inside the file.
What happens to your images
Your images are sent to our server only to compress them. The originals are deleted as soon as the process ends, and the result is available through a private link that's deleted automatically shortly after. We don't look at your photos or share them with third parties.
Frequently asked questions about compressing images
Does my photo's pixel size change?
Not at the low and recommended levels: the photo keeps its dimensions. Only the high level scales down images larger than 2560 pixels per side.
Does the format change?
No. Each image keeps its format. If you want to change it, use Convert images.
Do photos come out straight?
Yes. Phone photos are straightened according to the orientation they were taken in before being compressed.
Can I compress animated GIFs?
Not yet. The tool works with JPG, PNG and WebP.
Does it cost anything?
No. It's free with no sign-up. The site is supported by ads.
