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 Stereo Mono Converter Online
Create a mono average, copy/fill stereo channels, select only the left or right channel, or swap the first two channels. The chosen mode changes the actual WAV channel data rather than just its playback display.
- Choose the source audio and channel operation.
- Select 8-bit or 16-bit PCM output.
- Process and listen to each output channel. A mono input is duplicated when stereo fill is selected.
Practical guide
What to check in the result
Stereo extraction/swap uses the first two decoded channels. Mono mixdown is a simple average, not a surround-standard downmix; opposite-phase content can cancel.
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.
