HOW DO I MAKE FILES SMALLERRR

I'm trying to upload a bunch of photos right now, but a lot of them say that the file is too large. How would I go about making them smaller

You could open them in an image editor like gimp or something and resize them. Gimp is free. If you need more help, don't be shy

If they are JPG and you dont want to resize them. extend them to PNG PNG have less bytes then JPG

@frotix, that advice is incorrect. PNG uses lossless image compression. JPEG is lossy. It doesn't save the image pixel for pixel and based on the quality you set will discard a varying amount of information as part of its compression to shrink the file. When it comes to photos you're practically guaranteed that the JPEG will always be smaller. Usually significantly so. And the ability to lower quality also makes them smaller.

while I agree with you guys.. 9 times out of 10, pictures are way too big anyway.. who looks at 1600x1400 pictures anyway? -_- I just resize them.

@ daniel friesen Don't most file compression cause loss of details just as much as expansions do? The programs that resize tend to just extend the pixel info alrdy there and the focus gets lost a bit depending on the manipulation of it. Some programs try to fix this but not all ... I don't know if all the free ones are like that though. And changing file extensions doesn't always work out either ... that's why I love pdf

@boundbyluck Generic file compression (gzip, deflate, bz2, etc...) don't lose any detail, they expand to the same data. If they didn't they'd be worthless. Exactly how they do this is a long and very technical explanation that varies by algorithm and wouldn't fit here. Lossless image compression algorithms like the one used in PNG does something similar but for 2d image data rather than textual data. However while lossy image compression algorithms like the one used in JPEG do use similar techniques to slightly reduce the file size but they also try and discard details in the image they don't think you'll notice in order to make the image smaller. (This is why you want to avoid modifying JPEGs over and over, because they discard a little bit of the image details each time you save) However I think you're confusing compression (reducing the raw byte size of an image without reducing the resolution) with image resizing (shrinking to different dimensions) which will of course lose data no matter the format because you're changing the dimensions.

@Mikorin ;) The Nexus 6 has a 2560x1440px screen, letting you see all the details in the photo – even though most websites aren't programmed to take advantage of this.
