The Nashi toolbox
27 tools. Room to create.
The shared Mac and Windows tool catalog. Native platform details are listed below.
Compress
Image, video, audio and PDF compression. Choose quality, reduction percentage or target size where supported. An unreachable target returns an explanation rather than silently losing features.
Metadata
Inspect, edit or remove supported image, PDF and media metadata, including track and chapter fields. Export a new copy.
Edit image
Resize, rotate, flip and tune brightness, contrast and saturation, with an original/result preview.
Annotate
Independent freehand/marker and shape tools, text, arrows and Select / Move. Choose one drawing tool at a time.
Frame image
Create a polished image frame with configurable padding, background, corners and shadow.
Crop image
Drag to select, move or resize the crop. Hold Shift to lock its ratio; Return exports a cropped copy.
Normalize audio
Analyze loudness, then export with integrated-loudness, loudness-range and true-peak targets.
Remove audio
Create a silent video copy while keeping the video stream.
Trim video
Preview, drag In/Out handles, move the selection and export its range. Keyboard playback, seeking and I/O marks help refine cuts.
Split PDF
Split selected pages into individual files or groups. Specify page ranges and pages per file.
Organize PDF
Reorder, remove and rotate pages. Optional uniform-width output is limited when document features cannot be safely preserved.
Extract archives
Extract ZIP, TAR, GZIP and RAR into a new folder. Path and link validation keeps entries inside that folder.
Images to PDF
Combine selected images into a new PDF in the chosen order.
Merge PDFs
Combine several PDFs while preserving supported page content and navigation. Originals remain unchanged.
Crop video
Select a region directly on the video preview. Drag, resize, use Shift ratio lock and Return to export.
Change speed
Change video speed with matching audio tempo and preview controls.
Join videos
Join multiple clips in order, adapting geometry, frame rate and audio layout to a consistent output.
Video snapshots
Choose timestamps and save still frames as new PNG files.
Split video
Split at markers, equal clip counts or intervals. Remove unwanted segments; save separately or join retained clips.
Audio to video
Create a waveform, spectrum, frequency-bar or still-image video from an audio file.
Trim audio
Waveform preview, In/Out handles and selected-range playback. Optional silence trimming and keyboard seeking.
Audio channels
Convert mono/stereo and set left/right levels, with channel previews.
Create collage
Arrange several images in a configurable layout with gaps and background styling.
Redact image
Select areas and export with solid, blur or pixelation treatments. Always verify the resulting file before sharing.
Redact video
Define rectangular regions and time ranges for solid, blur or pixelated redaction.
Redact audio
Choose intervals to replace with a bleep or silence; preserve the rest of the audio.
Read QR codes
Scan supported images and PDF pages, review detected contents and export a report.
A native preview. A familiar flow.
Images
PNG, JPG, BMP, GIF and TIFF conversion, with PDF export. Resize, crop, rotate, horizontal flip, independent marker/rectangle annotation, JPEG compression and metadata removal. GIF import uses its first frame.
Media
Video/audio conversion plus 15 tools: compression, metadata removal, loudness normalization, mute, video trim/crop/speed/join/snapshots/split/redaction, audio visualization, audio trim/channels/bleep. Export uses verified FFmpeg; native playback depends on Windows codecs.
PDF & ZIP
Merge PDFs, split pages and reorder selected page numbers. Create ZIPs from files and extract ZIPs with traversal/link checks, entry limits and expansion limits. Existing names are kept.
The everyday controls
Mac-style Home and searchable Library, with System/Light/Dark appearance. Drop files or paste text, images and files with Ctrl+V. Ctrl+O chooses files; Ctrl+Space opens tools; Ctrl+2 opens Library; Ctrl+F searches. Clipboard imports and Library survive app updates. Space plays/pauses; Left/Right seek 1 second; I/O set a media range. Crop uses drag, Shift ratio lock and Enter. Escape closes the editor. Public-link video/audio/thumbnail downloads and signed public updates are included.
The Windows parity build adds Explorer drag wheels, Float, folder automation, Office/Pages conversion, QR reading, background removal and eight window layouts, including Maximize. AirDrop is replaced by Windows Share; system permissions, codecs and native dialogs follow each OS.
A link. A file. Yours to work with.
Paste a public video share link or direct media address. Choose video, MP3 or the original image/media, quality and destination. YouTube cards can offer video and thumbnail separately; Instagram reel cards need an actual reel link.
Use Control–Shift–D for a copied link, drag a browser card with Command, or drop it onto Home. Some players only expose a poster or blob address; Copy Share Link is the fallback. Supported sites change. Instagram photo posts open a photo picker; selected photos are saved in post order. Reels offer video and audio without a thumbnail action. DRM, live streams, login-required media, profile-wide downloads and video playlists are not supported.
Formats, without the guesswork
45 inputs. 275 routes.
This table is generated from the app catalog. A format appearing here does not mean every advanced document feature can be retained. PDF to DOCX/XLSX reconstruction is heuristic; PDF to PPTX uses page images.

Six ways to keep files moving.
AirDropFloatCopyMoveCopy pathOpen in Terminal
Float keeps files in a small shelf. History can be searched, reused and revealed in Finder. Move explicitly moves originals; exports create new copies and do not overwrite existing names.

- Drag an image in Finder while holding Shift.
- Drop on JPG in the conversion wheel to create a new copy.
- In Crop Image, drag a selection. Shift locks the aspect ratio; Return saves a cropped copy.
- Drag a video while holding Command, then choose Trim Video. Space controls playback; drag In and Out to set the range. Preview it and save a fresh trimmed copy.
- Find the outputs in Freshly made and Finder. The demo creates a JPG, a 410×410 crop and a 7.07-second trimmed clip from a 12-second source; originals remain unchanged.
Mac screenshots: 0.7.3. Windows screenshot: native UI test capture of released 0.7.5, verified in PR #1. Demo files use Nashi artwork only. Click any screenshot to see it in full.

Clear boundaries.
Privacy
Conversion and editing run locally. Web downloads contact the chosen site. No analytics, cloud account, browser-cookie import or subscription is built in.
Signed updates
Official public updates require no GitHub token. macOS verifies its signed feed and archive; Windows verifies its archive signature and version. Active jobs finish before the app restarts.
Transparent limitations
Complex document conversions are best-effort. Haptic feedback depends on hardware. macOS and Windows may show first-run warnings for builds without an OS-trusted publisher signature. We do not ask you to disable system security.
