Shrinklet Support
Everything you need to compress PDFs, images, videos, and audio with confidence.
This guide walks through the full Shrinklet workflow: adding files, choosing presets, tracking progress, reviewing savings, sharing results, and using advanced settings when you want more control.

Jump to a topic
Start with the clean drop zone, then drag in PDFs, images, videos, or audio when you are ready.
Quick start
Use this path when you just want to make files smaller without thinking through every setting.
2
Pick a preset
Choose Light, Medium, Strong, or Maximum based on whether you care more about quality or file size.
3
Compress and save
Click Compress, watch progress, then save or share the compressed output when Shrinklet finishes.
Full workflow guide
The screenshots show the real app flow from an empty screen to a completed batch.
01
Start from the drop zone
The home screen keeps the next action obvious. Drop files into the center area to begin.
02
Review the file before compression
For a single file, Shrinklet shows the pending item, its current size, and the selected compression option so you know what will happen before you run it.
03
Track progress
During compression, the progress indicator and percentage make it clear that Shrinklet is actively working.
04
Review the result
After compression, Shrinklet shows the new size and savings so you can decide whether the result is good enough or whether to try another preset.
05
Compress mixed-media batches
You can queue multiple PDFs, images, videos, and audio files together. Batch mode helps when you need to prepare several files for email, upload, storage, or sharing.
06
Compare savings per file
Completed batches show each file’s output and savings, making it easier to spot which files compressed well and which may need different settings.
Choosing a compression preset
Start with Medium for everyday use. Move up or down depending on how the file looks and how small it needs to be.
Light
Best when visual quality matters most and you only need a modest size reduction.
Medium
The best default for most documents, images, videos, and audio. It aims for a balanced result.
Strong
Use when file size matters more, such as uploads with strict limits or files you need to email.
Maximum
Use when you need the smallest practical file and can accept more quality tradeoff.
Custom
Use advanced settings when you want direct control over quality, image resolution, and output behavior.
Try again anytime
When a result is too large or too soft, run the original through another preset to compare outcomes.
Review results before sharing
Shrinklet now includes a Review Result flow for documents, images, and audio so users can verify quality before replacing or sending a compressed file.
PDF review
Compare the original and compressed PDF side by side, zoom in, and read pages before sharing.
Image review
Zoom in on the original and compressed image to check detail, edges, and small text.
Audio review
Listen to the original and compressed audio output using native playback controls.
Share output
Use the native share sheet to send compressed files through AirDrop, Mail, Messages, Notes, and more.
Media-specific settings
Most users can stay with a preset. When more control is needed, Shrinklet separates settings for output, PDF, video, audio, statistics, help, and about.
Output and naming
Choose the save location, overwrite behavior, and filename suffix.
PDF cleanup
Remove metadata, annotations, page thumbnails, and hidden layers when appropriate.
Video output
Set max resolution, frame rate, and video metadata removal.
Audio output
Adjust bitrate, sample rate, channels, and audio metadata removal.
What each screen is for
Use this section as a visual map of Shrinklet.
Single file review
Confirm the selected file and compression preset before starting.
Progress view
Watch the active compression step, progress bar, and percentage.
Share menu
Use the share action to send or move compressed files quickly after completion.
Advanced settings
Fine tune quality and compression behavior when presets are not enough.
Troubleshooting
Most issues can be resolved by changing the preset, checking the original file, or trying a smaller batch.
The file did not get much smaller
Some PDFs, images, videos, and audio files are already optimized. Try Strong, Maximum, or Custom settings. Scanned PDFs, image-heavy documents, high-resolution images, long videos, and large audio files usually show the biggest savings.
The output looks too soft
Use Light or Medium, or increase quality/resolution in Custom settings. Smaller files usually require some visual tradeoff.
Compression feels slow
Large PDFs, high-resolution images, long videos, large audio files, and big batches take longer. Try compressing fewer files at once or closing other heavy apps.
A file fails to compress
Make sure the file opens normally in Preview or another Mac app. Damaged, password-protected, or unusual files may not compress correctly.
I cannot find the output
Check the save location you selected after compression. Use the completed result screen and share menu to move or send the file again.
I need the smallest possible file
Choose Maximum or Custom, then lower image quality and resolution. Review the output carefully before sending important documents.
Privacy and offline use
Shrinklet is designed for local Mac workflows. Your PDFs, images, videos, and audio files are compressed on your Mac, which helps you avoid uploading private documents to random web tools. App Store purchases, downloads, and refunds are handled by Apple.
- Use Shrinklet for PDFs, common image files, videos, and audio files.
- Keep an original copy of important files before replacing or sharing compressed versions.
- Review compressed output before submitting legal, financial, school, or business documents.
