Not sure where to start?
A photo must fit both pixels and KB
Read the upload form's required dimensions, format and file-size limit first. Resize the image to the correct dimensions, then reduce its KB size if needed. Small size targets can reduce dimensions again, so check the downloaded result against both limits.
Several documents need to become one PDF
Use Merge PDF for existing PDFs. For photos or scans, use JPG to PDF instead. Add files in the required order and review every output page. Converting a photo into a PDF does not recognize its text.
A PDF exceeds a file-size limit
Start with Compress PDF and choose clean re-save if searchable text matters. Strong image compression can make scans smaller, but can remove selectable text and form fields. Keep the original and inspect small print, signatures and codes after downloading.
Check the result before submitting
FileHoney prepares files; it cannot guarantee that a receiving website will accept them. Confirm the actual file size, dimensions, page order and readability. For passport or application photos, follow the receiving authority's current instructions rather than relying on a preset.

About Compress Audio Online
Create compact Ogg Opus audio with a selected bitrate, or explicitly export PCM WAV. Opus is the default and keeps the decoded channel count and full duration; its encoding/playback rate is 48 kHz. Actual source/output bytes and delivered bitrate are reported. Keep original bytes avoids another lossy generation when no conversion is needed.
- Choose the audio source and note its original file size.
- Choose Ogg Opus and its bitrate, PCM WAV and bit depth, or Keep original bytes. Keep channels/rate unless a change is needed.
- Process and compare measured output bytes, duration and channels. Listen to the downloaded result.
Practical guide
What to check in the result
Opus encoding needs a browser with WebCodecs AudioEncoder support and mono/stereo input. It is lossy; lower bitrates trade detail for size. WAV and original-byte delivery remain available. MP3 and AAC encoding are not provided, and no fixed percentage reduction is guaranteed.
Large recordings and channel data
Processing happens in browser memory. Decoded inputs and outputs are limited to 32 million channel samples, roughly 128 MB of floating-point audio. Shorter recordings or fewer channels reduce memory use. Preserve an original copy and listen to the exported result.
