Sizora: Batch Image Resizer

The form says "max 500 KB", the email is too big, WhatsApp makes your photos blurry? Sizora gets your photos just under the limit – at the best possible quality. No video ads between steps, no subscription, no limits. While Sizora works, all you see is the progress. 🎯 Target size in KB or MB • Enter a limit like 50 KB, 500 KB or 2 MB – Sizora finds the highest quality that fits (binary search) • Only when there is no other way does it lower the resolution – never needlessly blurry • For a whole batch: "Email · 18 MB total" splits the limit across all photos • 1 KB = 1000 bytes, so it also fits forms that count 1024 • Minimum size for exam portals ("photo 20–50 KB"): photos that are too small get padded ✨ Automatic quality • No slider needed: Sizora picks the smallest quality that still looks like the original – per photo • "Free up space": same size or max. 4K in one tap 📋 Ready-made presets • Photo for online application forms (50 KB), signature (20 KB), under 200 KB, 500 KB, 1 MB • Upload portals (5 MB) • Email: 2 MB per photo or 18 MB in total (fits Gmail, Outlook.com and most providers) • Passport 35 × 45 mm and US visa 2 × 2 in – with assistant (face, head size, white background) and 10 × 15 print sheet • HEIC, PNG or WebP to JPG in one tap (for forms, printers, older phones) • WhatsApp (1600 px), WhatsApp HD, Instagram 1:1 and 4:5, Story 9:16, YouTube thumbnail • Save your own presets – and start them from the app icon 📄 PDF • Photos of papers become one PDF under your limit (2, 5 or 7.5 MB) – and existing PDFs can be shrunk or merged • ID card copy: front and back at original size on one A4 page; also 2 or 4 images per page • "Document" mode: paper turns white; for signatures Sizora trims the border automatically • Pages of a PDF: remove, rotate, reorder 📐 Resize your way • Percent, width × height, longest or shortest side, megapixels – also in mm, cm or inches with DPI • Fit, fill (crop), with border (white, black or blurred) or stretch to exact size • Crop and rotate: all photos to 1:1, 4:5, 3:4 or passport format – or each photo by hand • Real preview before saving: result, size and resolution side by side • Size and expected result on every thumbnail, sort by size • Format: like original, JPEG, PNG or WebP; HEIC and AVIF photos from Samsung and iPhone become JPEG 🧾 Right inside web forms • Tap "Choose file" in your browser → Sizora: pick or take a photo, choose the limit – the small file (also as a PDF) goes straight into the form 📚 Batch without limits • As many photos as you like: from the photo picker, as files, a whole folder or straight from the camera • In your gallery: select → Share → Sizora • Keeps working in the background, cancel any time 🗂 Your photos stay organized • Originals only change if you ask; results go to the "Sizora" album, a folder of your choice or next to the original • Move originals to the trash (restorable for 30 days) or replace them with the small version • Share all results at once – or as a ZIP • Never larger than the original: if a photo wouldn't get smaller, the original stays • File names stay recognizable (IMG_1234_small.jpg), the date taken is kept – your gallery sorts correctly • Portrait photos are always upright 🔒 Metadata (EXIF) your way • Keep everything (date, camera, location), remove only the location, or remove all • Ideal before sending photos or uploading them online 🔍 Before / after • Compare the result with the original using a slider and zoom, size and resolution at a glance • Share one or all at once 🔒 Offline and private • Everything happens on your phone – no upload, no account, no watermark, no advertising ID • No storage permission needed (Android 10+) Sizora is free and supported by one small banner ad on the start, result and settings screens (Google AdMob, with your consent where required).
