How do I make an Instagram carousel from a wide image?
Use Krymp's image splitter and pick the Carousel mode: set the number of slides (2–10), choose portrait (1080×1350) or square, and tune the overlap so swipes flow together. Everything runs locally in your browser.
Where is text cropped when I post into Instagram's profile grid?
Instagram's profile UI crops roughly the top and bottom 18–23 % of each grid tile. Keep text and key elements in the middle. Krymp's image splitter has a Safe zones overlay that shows exactly where.

Under the result in Krymp's image splitter you'll find a Caption pack, shortcut buttons to Buffer/Later/Meta Business Suite and a poster PDF (A3/A4) with crop marks — all without the image leaving the browser.

image compression
How do I compress an image for free without losing quality?
Drop the image into Krymp, pick a target size (e.g. 1 MB or 100 KB) and download. Everything runs locally in your browser — no account needed.
How much can I compress an image without losing quality?
Photos (JPG/WEBP) tolerate a 60–80 % size reduction without a visible difference. Graphics and screenshots (PNG) tolerate 20–40 %. Lossless compression always gives 10–30 %.
How do I shrink a PDF file without losing readability?
Upload the PDF into Krymp and pick a compression level. Text stays vector and searchable; only embedded images are compressed. Files typically shrink 40–80 %.
How do I compress a PDF on iPhone without an app?
Open krymp.hasty.se in Safari on iPhone, drop in the PDF (or pick it from Files), choose a compression level and save. No app, no account, no upload to a server.
How do I compress a PDF on Mac without installing anything?
Open krymp.hasty.se/en/pdf in Safari, Chrome or Edge on your Mac, drag in the PDF and pick a level. No Adobe account, no install, and the file never leaves your computer.
Why is my PDF so large and how do I fix it?
Large PDFs are almost always caused by high-resolution embedded images or scanned pages. Compress the images or lower the DPI and the file typically shrinks 50–80 %.
Is it safe to compress a PDF online?
On Krymp it's safe — all compression happens locally in your browser with WebAssembly. Files are never uploaded to a server. Other services vary; read their privacy policy.

video
How do I compress a video so it fits in an email?
Use Krymp's video tool, pick 720p or 480p and a lower bitrate. Save as MP4 (H.264) to clear Gmail (25 MB) and Outlook (20 MB).
How do I compress a video for WhatsApp?
WhatsApp has a 16 MB video limit. Compress to MP4 H.264, 720p, ~1 Mbit/s — then 1–2 minutes fit without a visible quality loss.

JPG, PNG, WEBP, AVIF, HEIC, TIFF, BMP, GIF and SVG. You can compress within the same format or convert between any combination.
What's the difference between JPG, WebP and AVIF?
JPG is universal but largest. WebP is ~25 % smaller at the same quality. AVIF is ~50 % smaller but slightly slower to decode and unsupported by older browsers.
What's the difference between JPG, PNG, WebP and AVIF?
JPG/WebP/AVIF fit photos (lossy, small files). PNG/WebP fit graphics and transparency (lossless). AVIF is smallest, JPG most compatible. WebP is today's best compromise.

audiogram
What is an audiogram?
An audiogram is a short video that visualizes audio (podcast clips, quotes, interview answers) as an animated waveform with a title — made for Reels, TikTok, LinkedIn, Shorts and YouTube where video is required or sound plays muted.
How do I make an audiogram for free?
Go to krymp.hasty.se/en/audiogram, drop in an mp3/wav, trim to 25–60 s, pick a format (9:16 for Reels/TikTok) and theme, turn on AI captions if you want, and hit Export. No account, no watermark, no upload.
How do I make an audiogram for my podcast episode?
Cut out the strongest quote (30–45 s), pick 9:16 for Reels/TikTok or 1:1 for LinkedIn, run AI captions for word-pop captions and export MP4. The whole process takes 2–3 minutes at krymp.hasty.se/en/audiogram-podcast.
Which audiogram format works best for Instagram Reels and TikTok?
9:16 (1080×1920) MP4 at 30–60 seconds. Place captions at mid-height so the text isn't hidden by the platform UI. Krymp has 9:16 as a one-click preset.
Is there an audiogram tool that supports Swedish?
Yes. Krymp Audiogram is fully Swedish-capable, free and account-free. AI captions support Swedish (å/ä/ö) and Swedish captions can be imported as SRT/VTT or written manually.
Is there an audiogram tool that doesn't require registration or an account?
Yes. Krymp Audiogram (krymp.hasty.se/en/audiogram) requires no account, no email and no payment method. No watermarks on output.
Can I get automatic captions on my audiogram?
Yes. Krymp Audiogram has AI captions that time-stamp the words and show them word-by-word (word-pop). You can also import SRT/VTT or write captions manually.
Which file format should I export the audiogram in?
MP4 (H.264) is the safest choice — it works on Instagram, TikTok, LinkedIn, YouTube and X. WebM is smaller but not universal. GIF for places where video doesn't work. WAV gives audio only.
map
How do I make a stylized map image of an address or city?
Open Krymp Map, search for the address, pick one of five styles (Noir, Pastel, Blueprint, Krymp, Warm) and a format (1:1, 9:16, A4, A3 or circle) and export as PNG, JPG or PDF. Everything runs in the browser.
Can I use an OpenStreetMap map from Krymp in a commercial project?
Yes. OpenStreetMap data is ODbL-licensed and allows commercial use as long as you credit '© OpenStreetMap contributors' in the caption, footer or on the back of printed material.
What keyboard shortcuts does Krymp Map have?
T = next theme (Shift+T = previous), R = random theme, F = favorite-pin current theme, M = new marker at center, +/− = zoom, ⌘/Ctrl+S = export, ⌘/Ctrl+K = copy share link, ⌘/Ctrl+Z and ⇧⌘/Ctrl+Z = undo/redo, ? = show help overlay.
