Typical jobs it solves: • Email attachment too large: compress photos to 100 KB or a PDF to 1 MB • Job application: shrink your CV or certificate PDF to the portal's limit • Send a video that is too big for chat: make the MP4 smaller in one step • Resize an image to exact pixels for a profile photo, form or website Hit an exact size: • Set a target in KB or MB and get a file that fits • Choose exact pixel dimensions for photos and videos • Presets for 50 KB, 100 KB, 200 KB, 500 KB and 1 MB • Compare before and after with a live preview Every file you need to send: • Photos: JPG, PNG, HEIC, WEBP, AVIF, SVG and more • Documents: PDF, Word, Excel and PowerPoint • Video and audio, including format conversion • Scan paper documents straight to a multi-page PDF Built for upload limits: • Smart Fix reads the requirements from a screenshot and prepares matching files • Batch several files in one run • Save to Files or Photos, or share directly Privacy comes standard: • Files are processed on your device and never uploaded • Works completely offline • Review and remove metadata such as GPS before sharing • Blur or pixelate faces, text and license plates in photos and videos Edit before you export: • Crop, rotate and resize images • Trim, crop, rotate or mute videos • Edit, annotate and sign PDFs and scans Formats it opens: • Images: JPG, PNG, HEIC, WEBP, AVIF, GIF, TIFF, BMP, SVG and camera RAW • Documents: PDF, Word (DOCX), Excel (XLSX) and PowerPoint (PPTX) • Video: MP4, MOV, M4V, 3GP, MPG and MPEG • Audio: MP3, M4A, AAC, WAV, AIFF, FLAC and OGG • Some formats depend on the codecs your device supports In three steps: • Add files from your photos, your file manager or another app's share menu • Set the goal: a size in KB or MB, exact pixel dimensions, or a preset • Check the preview, then save a new file or share it straight away Good to know: • No account, no sign-up and no cloud — it works in airplane mode • Your originals are never overwritten; every result is a new file • Batch mode applies the same target to many files in one run • Quality stays as high as the target size allows, and you see it before saving Selected files and their contents are processed on your device and are not uploaded to a server. Detection results are suggestions and can miss content, so always check the preview before exporting. FileSizeFix is free with no limit on how many files you compress. Ads keep it free: a short full-screen ad runs while a job is processing, and the finished files are ready the moment it closes — saving, exporting and sharing are never interrupted by advertising. FileSizeFix Pro is an optional auto-renewing subscription, monthly or yearly, that removes all ads — every tool stays available either way. Prices are shown before purchase and may vary by country. The subscription renews automatically unless canceled and can be managed in your store account settings.
