They do NOT protrude on the other side.
EDIT: I should have mentioned that I WAS able to pry some of them out. It was just super difficult.
I think you said pliers weren’t doing the job. Grab them with vice grips (locking pliers) and use the claw side of a hammer to pull them off like a nail.
That is smart AF
Needle nose pliers or dykes
Dykes?
Straighten them out. Cut them leaving no less than 1/4". Then hammer them through the other side. Then use your channel locks to pull them out.
I’ve saved hundreds of sheets of plywood doing this.
Use this type of hammer and pull with claw side.
Those look like brads to me. They may have been glued brads. I use channel lock pliers to pull them out. The curved jaw gives good leverage.
This is exactly what I used. Worked perfect.
Brilliant! I actually have exactly this. Cheers!
I’d just grab em with some pliers. Maybe needlenose depending on how small and how the space is.
They have stubbornly defeated my plier-based efforts
Maybe try some vice grips?
What if you were to use a hammer also? Like, use it like you would to remove a nail, but put a pair of vice grips right above the claw to keep it from just sliding
Use another tool to act as a fulcrum so you can use the pliers as a lever
Is it possible that they are brads from a nail gun? Are there tiny marks on the opposite side? Those nails don’t have heads you can grip, but you wouldn’t be able to pull them through.
If so, you may be able to push them back where they came from using the pliers.
There is absolutely no sign of them on the other side
I use needle nose pliers, grab the brad as close to the hinge as possible and flat against the board. Then, grab tight and use the tip of the pliers as a fulcrum.
Angle grinder will take care of those in seconds!

Pair of linesman pliers or needle nose vise grips a block of something to create leverage and use that lever.
I always use end nippers. They look like something a horse farrier would use to trim hooves. They have a round face so you can grab at the base of the nail and rock it back with ease. Nothing I have found beats them for speed and ease of use when you’re pulling nails/staples through the back of wood.
If you want to do minimal damage, try backing them out the front side with vice grips like another commenter suggested.
They aren’t at all visible on the front if they are even there. I don’t think they even come through on the front. I’m definitely adding the nippers to my list.
If you don’t care about metal in the wood, the you could use a pair of diagonal cutters to snip them flush with the wood rather than try to extract them.
I care SO much. It’s not in me to leave a perceived problem unsolved in my own home.
Knock them backwards/through or grind them off.
brads or finishing staples tend to be set below grade on wood. if you back them out the way they went in, you have about a 100% chance to blow out a chunk of wood on your finished side.
use end nippers, needlenose vice grips, or channel locks to pull them through the rest of the way. the staples/brads are designed to go one direction.
if you’re pulling them out of another finished side, you can use a flatbar under your nippers to protect the wood and roll against the flatbar. you could probably use some thick leather or rubber too.
If pliers didn’t do the job, I would cut them at the base and sand them down to be smooth and flush with the wood.
A Dremel would cut those out nicely.
Sometimes the wood closes over them after the last sanding when assembled.
