Five qualifying smaller copies. No subscription. See trial details.

Create smaller copies of supported files without changing their format.

Make a smaller copy for sharing
Start from File Explorer and keep the original for later editing.
- Right-click your file, open Make Smaller and choose Preserve quality.
- If you need more reduction, try Balanced or Smallest size from the original. These profiles can reduce quality or resolution.
- Use Show in folder to open a successful copy. Check its appearance or playback and file size before sending it.

Before you choose
- A supported extension does not guarantee that every file structure or codec can be processed. Some files are already efficiently compressed; no smaller copy may be created.
- Balanced and Smallest size may reduce quality or resolution in supported content. They do not guarantee a smaller result than Preserve quality for every file. Review the actual method and changes before sharing.
- There is no target-MB setting. Originals remain, so creating smaller copies uses additional disk space; it does not automatically free space on your PC.
Choose a quality profile
Preserve quality
Start here when keeping the existing quality matters. The app uses methods that do not add quality loss; some files have little or no room to shrink.
Balanced
For everyday sharing when some quality loss is acceptable. Supported images, audio or video may be recompressed or resized within the profile limits.
Smallest size
Allows stronger quality or resolution reductions in supported content. Check the copy carefully, especially small text, image detail and sound.
The selected profile is a preference, not a promised output size. A file can use the verified lossless method when the quality-reducing method is not suitable. The result explains what was applied.
Compare the three profiles →Supported file families
Support depends on the file contents as well as its extension. Review the applied method and any skipped items in the result.
Images
JPEG (.jpg, .jpeg, .jpe, .jfif), PNG/APNG, WebP, GIF, BMP, TIFF (.tif, .tiff), AVIF and HEIC/HEIF.

Audio

Try it with your own files
Try Make Smaller free. Five saved copies that are at least 1% smaller count toward the trial allowance.
Each qualifying file counts separately, including files in a folder. Failed, cancelled or unverified attempts use no allowance. A valid saved copy below 1% reduction does not count.

More about Make Smaller
Features and working limits
- Start in File Explorer: Select supported files or folders, right-click and open Make Smaller. Choose Preserve quality, Balanced or Smallest size.
- Keep your originals: Successful results are separate copies in the same format. The app checks each candidate before saving it; files that cannot be reduced enough receive an explanation.
- Process a folder at once: If asked, choose Include subfolders or This folder only. Review each result and use Show in folder to locate a smaller copy.
Local data and network use
- File reading, compression and output verification run on your PC. Selected files are not uploaded for processing.
- Local trial usage and recovery records keep track of the five-use allowance for the same Windows user and app package family. They survive ordinary app uninstall, reinstall and reset. Clear history does not reset the allowance. This is not an account-wide or cross-device quota.
- Original files remain unchanged. Smaller copies are separate files; stopping a run does not delete copies already created.
- Recent results history keeps up to 10 completed runs from the last 30 days, including file names, paths, sizes, methods and outcomes. Clear history removes the displayed result records, not originals, smaller copies or recovery records.
- A separate local PDF decision cache stores content-derived hashes, sizes and processing decisions for up to 30 days, with a limit of 256 entries. It does not store source names, paths or file contents and is separate from visible history.
- Local processing can create temporary files and recovery records. Startup diagnostics can contain error messages and technical details, including paths mentioned in an error. Review any information before sending it to Support.
- Microsoft Store services check trial or full-version access, handle purchases and provide Store updates. Buy full version opens the Store purchase flow; access changes only after Store confirms the full license.
- Support opens the Osenpa website. Store actions use Microsoft Store; compression itself does not upload the selected files.
System requirements
Windows 11 version 24H2 (build 26100) or later; x64; Microsoft Store installation; readable local source files, a writable output location, and enough free space on the system and destination drives for processing and separate copies.
