Google Photos is one of the most popular ways to back up and organize photos, but storage fills up faster than most people expect. Understanding how Google Photos handles image sizes — and knowing how to reduce file sizes before uploading — can save you from hitting the 15 GB wall and keep your library manageable for years.

Google Photos Storage Overview

Every Google account comes with 15 GB of free storage, shared across Google Drive, Gmail, and Google Photos. Once you exceed this limit, new uploads are blocked until you either delete files or upgrade to a Google One plan:

100 GB — suitable for most casual smartphone photographers
200 GB — comfortable for users who shoot frequently or keep video
2 TB — for heavy users, families sharing storage, or those with large RAW archives

Important change since June 1, 2021: All photos and videos uploaded after that date count toward your storage quota, regardless of resolution or upload quality. The previous "free unlimited High Quality" perk no longer applies to new uploads.

Two Upload Quality Options

Original Quality

With Original quality, Google Photos stores your image exactly as it was captured — same resolution, same file size, same EXIF metadata.

A 12 MP smartphone photo at ~5 MB uses ~5 MB of your storage quota
A 45 MP mirrorless RAW file at ~40 MB uses ~40 MB
Best for: professional photographers, anyone doing serious editing, archivists who want pixel-perfect backups
Counts fully toward your storage quota at the actual file size

Storage Saver (formerly "High Quality")

Storage Saver is Google's compressed upload mode. Google recompresses your images to fit within their quality threshold before storing them:

Photos above 16 MP: Google downsizes them to approximately 16 MP (roughly 4920×3264 px for a 3:2 aspect ratio, or 4920×2768 for 16:9). This is still large enough to print at 16"×12" at 300 dpi.
Photos at 16 MP or under: stored at full resolution, but Google applies JPEG compression. The visual difference is generally undetectable on screen.
Videos above 1080p: compressed to Full HD (1920×1080). 4K videos are downscaled significantly, which may matter if you plan to edit or reuse the footage.
Google's compression algorithm is generally excellent — most people cannot tell the difference when viewing on a phone or monitor.
Storage Saver files use less quota than Original — good for heavy smartphone users

Note: Google discontinued free unlimited Storage Saver uploads in June 2021. Storage Saver uploads still count toward your quota now, but they use less space than Original quality because of the compression applied.

How Much Storage Does a Typical Photo Use?

Smartphone photo (12 MP, JPEG): 3–6 MB in Original; approximately 1.5–3 MB in Storage Saver
High-res DSLR JPEG (24 MP): 8–15 MB in Original; approximately 3–6 MB in Storage Saver
RAW file (from DSLR or mirrorless): 20–50 MB in Original; Storage Saver converts these to a compressed JPEG equivalent of roughly 2–5 MB
4K video (1 minute): 300–600 MB in Original; 60–150 MB in Storage Saver (downscaled to 1080p)
Screenshot (PNG, 1080p phone): 0.5–2 MB in either mode — Google treats screenshots similarly to photos

Tips to Save Google Photos Storage

Switch to Storage Saver if you are filling up. The quality difference is minimal for everyday photos shared on social media or viewed on screens. You can change this setting in Google Photos → Settings → Backup quality.
Compress images before uploading. Even in Original mode, a smaller JPEG file takes up less quota. Use the image compressor to reduce file sizes by 40–80% with no visible quality loss before you upload a batch.
Resize oversized images before uploading. If you shoot with a high-resolution camera (36 MP+) and only need the photos for sharing or screen viewing, use the image resizer to bring them down to 16 MP or less before upload. This eliminates Storage Saver's automatic downscaling and lets you control the output.
Delete screenshots, duplicates, and blurry photos. These all count toward your quota. Go to Google Photos → Library → Utilities → Manage storage to find and remove low-value files.
Use the Google Photos Storage Manager. Visit photos.google.com/settings to access the Storage Manager. Google automatically identifies blurry, dark, or very small photos and highlights them for deletion — a quick way to recover hundreds of megabytes.
Convert RAW files to JPEG before uploading. If you are not doing professional editing on the copies stored in Google Photos, converting RAW to JPEG saves 80–90% of storage per file. Use the image converter to convert RAW formats to high-quality JPEG before uploading.
Empty the Trash regularly. Deleted photos in Google Photos go to a Trash folder and stay there for 60 days, still consuming storage during that time. Empty Trash manually to reclaim space immediately.

What Resolution Should You Upload?

Smartphone photos: Upload as-is — modern phones produce well-sized JPEGs that fit naturally within the Storage Saver threshold. No pre-processing needed.
RAW files: If you are not doing professional editing on the Google Photos copy, convert to JPEG first. A 40 MB RAW becomes a 4–6 MB JPEG with no visible quality loss for sharing and screen viewing.
Screenshots: PNG is fine — Google Photos handles them well. Screenshots are typically small anyway.
Scanned documents or photos: 300 dpi for a 6"×4" print is 1800×1200 px (~2 MP) — well under 16 MP. Upload as JPEG at quality 85–90 for compact file sizes.
Maximum single file upload size: 200 MB per photo or video file.
