1How small?
Good quality and a much smaller file. Works for most photos.
Lower quality means a smaller file.
2What size?
Fill one box to keep the shape. Fill both to get that exact size.
Exact sizes are cropped from the center so nothing looks stretched.
3Which format?
JPG has no see-through areas, so those turn white.
Saving a new copy also removes hidden details like location.

Why Pixlume is different
Many online compressors upload your photos to their servers and limit you to small files or a few photos a day. Pixlume works inside your own browser, with no sign-up and no file size cap. It can also aim for an exact size in KB, which many online forms ask for. Read our Tools Terms for details.
Get the smallest file with the best look
Resize first
A phone photo is often 4000 pixels wide. Most websites show it at 1600 or less, so resizing saves the most space.
Try WebP
WebP files are usually smaller than JPG at the same look. Use JPG when a form or old app asks for it.
Need under 50 KB?
Choose Exact size in KB and keep the box ticked. Pixlume lowers the size step by step until it fits.

Is Pixlume really free?
Yes. Pixlume is free with no sign-up and no watermark. You can compress up to 20 photos at a time, as often as you like.
Are my photos uploaded anywhere?
No. Your photos are read and compressed on your own device. Nothing is sent to Digieh or anyone else.
How do I make a photo under 100 KB or 50 KB?
Choose Exact size in KB in step 1 and type your limit. If a form also has a minimum size, type it in the Min box. Keep the box ticked so Pixlume can make the picture a little smaller if needed.
What is the difference between compressing and resizing?
Compressing keeps the same width and height but stores the picture more efficiently. Resizing changes the width and height. Doing both gives the smallest files.
Will compressing lower the quality?
JPG and WebP lose a little detail when compressed, but the best balance setting keeps it hard to notice. Use the before and after slider to check. PNG keeps every detail but stays larger.
Does Pixlume remove hidden photo details?
Yes. Every new copy is saved without hidden details such as location and camera model. To clean photos without changing them at all, use our Cleanlume photo privacy cleaner.
Can I compress iPhone HEIC photos?
Not yet. On your iPhone, go to Settings, then Camera, then Formats, and choose Most Compatible to save new photos as JPG.
