iPhone storage is not freeing up even after deleting files

So, I’ve been trying to move a whole lot of big files from my iPhone to my non-Apple laptop by compressing the file and upload it to my cloud storage. Now, when I deleted the files, it’d free up the storage but when I deleted the compressed file, the storage didn’t budge and stay the same. I tried restarting my phone and it’s still the same. I thought I was tripping but no, I’ve been trying multiple times but the compressed files wouldn’t free up the storage so basically I’m back to square one here. I got rid of the big files but the compressed files wouldn’t free up the storage. Does anybody know where those compressed files went since it didn’t free up any storage? Thanks!
