The “storage full” notification always seems to hit at the worst moment — right before you need to take a photo, or right when a backup is trying to run. The instinct is to pay for a bigger plan. Before you do, it’s worth trying the cheaper fix first: a lot of that storage is being eaten by old photos and videos that are far larger than they need to be, and shrinking them can buy back real space for free.
Why This Actually Works
Both Google Photos and iCloud count file size directly against your storage quota — a 12MB photo takes up 12MB, whether or not you ever view it larger than a phone screen. Photos and videos from newer phones are often shot at resolutions and bitrates far higher than most people ever actually need for casual viewing or backup, especially for older files sitting untouched in your library. Compressing those files before re-uploading them can shrink your total storage usage substantially without meaningfully changing how they look on a screen.
This isn’t a trick or a workaround — it’s the same principle as how resolution actually affects file size: a photo has far more pixel data than a phone or laptop screen can display, and a lot of that extra data is invisible in normal use but still counts fully against your storage limit.
Before You Start: Back Up First
This workflow involves replacing files in your cloud library, so get this part right before touching anything:
- Download the originals you plan to compress — don’t compress-and-delete based only on what’s already in the cloud; keep an untouched copy somewhere else (an external drive, a separate folder) until you’ve confirmed the new versions look right.
- Work in batches, not your entire library at once — start with a folder of old photos or videos you’re confident you don’t need at full resolution (screenshots, old duplicates, casual videos), confirm the process works the way you expect, then continue.
- Only delete the old cloud copy after the compressed replacement is safely uploaded — never delete first and compress second.
Step 1: Compress Old Photos
AllMediaTools Image Compressor is free, works in the browser with no login required, and lets you control the quality/size tradeoff directly:
- Go to the Image Compressor page.
- Upload the photos you want to shrink.
- Choose a compression level — a moderate setting typically cuts file size substantially with no visible difference at normal viewing sizes.
- Download the compressed versions and re-upload them to Google Photos or iCloud in place of the originals.
If you’re working through a large folder rather than a handful of photos, batch compressing a whole folder at once covers the faster workflow for that.
Step 2: Compress Old Videos
Video is usually the bigger win here — a few minutes of old 4K footage can easily be several gigabytes, often stored at a much higher resolution or bitrate than the content actually needs. AllMediaTools Video Compressor handles this the same way, for free:
- Go to the Video Compressor page.
- Upload the video.
- Choose a compression setting appropriate for how you’ll actually use the file (casual viewing needs far less than something you plan to re-edit).
- Download and re-upload the smaller version.
Our guide on compressing video for size limits covers the same compression settings in more depth if you want the specifics on quality tradeoffs at different levels.
What to Target First
Not every file is worth the effort. These categories give the best return for the time spent:
| Category | Why it’s worth compressing |
|---|---|
| Old 4K or high-resolution video clips | Video is the single biggest storage consumer per file — often several GB each |
| Burst-mode photo sequences | Usually many near-identical shots at full resolution; compress (or delete duplicates) rather than keeping every one at full size |
| Screenshots and screen recordings | Rarely need to be kept at original resolution/bitrate long-term |
| Photos and videos older than a year or two | Lower likelihood you’ll ever need the absolute original quality again |
A Note on Google Photos Specifically
Since June 2021, Google Photos no longer offers a separate “free unlimited storage at reduced quality” tier — everything you upload now counts against your regular Google account storage (shared across Photos, Drive, and Gmail), regardless of quality setting. That change is exactly why compressing before uploading matters more than it used to: there’s no longer a built-in “storage-free” option to fall back on, so managing file size yourself is one of the few remaining ways to slow down how fast that shared quota fills up.
If You Still Need More Space
Compression buys you time and space, but it’s not unlimited — eventually an actively growing photo and video library needs somewhere to live. If you’re evaluating paid storage tiers or a dedicated backup service as the next step, our comparison of cloud storage services looks at the tradeoffs between the major options for anyone with a genuinely large, growing media library.
Frequently Asked Questions
Will compressing my photos make them look noticeably worse?
At a moderate compression setting, usually not — the quality loss is mostly in pixel-level detail that isn’t visible at normal viewing sizes (a phone screen, a shared photo, a printed 4×6). Very aggressive compression settings can introduce visible artifacts, especially in photos with fine detail or gradients, so it’s worth checking a few results before compressing an entire library at the most aggressive setting.
Does this delete my original photos?
No — compressing creates a new, smaller file; it doesn’t touch or delete the original unless you specifically delete it afterward. The recommended workflow is to keep a backup of the originals somewhere outside the cloud service until you’ve confirmed the compressed versions are uploaded and look right.
How much storage can I realistically free up this way?
It varies a lot by what’s currently in your library, but video is usually where the biggest gains are — a folder of old 4K clips compressed to a more reasonable resolution and bitrate can shrink dramatically in total size. Photos typically save less per file but add up across a large library.
Is there a way to do this automatically instead of one file at a time?
Batch tools that process a whole folder of images or videos at once are much faster than compressing files individually — see the batch compression guide linked above for the image side. There isn’t a way to compress files already sitting in Google Photos or iCloud in place; they need to be downloaded, compressed, and re-uploaded.
Should I compress photos before uploading them for the first time, or only old ones already in the cloud?
Both help, but compressing before the first upload is more efficient since you skip the download-compress-reupload cycle entirely. Going back through an existing library is the fix for storage that’s already full; compressing new photos and videos before they ever hit the cloud prevents the same problem from building up again.
Is compressing old files better than just paying for more storage?
It depends on how much storage you actually need long-term. Compression is free and can meaningfully delay needing to pay for anything, but if your library is large and actively growing, it’s a delay rather than a permanent fix — at some point a bigger storage tier or a dedicated backup plan becomes the more practical option.
